A tomato processing line seasonal shutdown should finish with verified cleaning, equipment-specific preservation, a repair plan, and a documented restart sequence. Remove product residues, establish the required storage condition for each machine, protect exposed interfaces, and assign inspections throughout the idle period.

Before the next tomato campaign, restore the line in stages: review its condition, close maintenance work, confirm utilities and controls, complete the required cleaning and hygiene checks, then verify production performance.

Use the installed equipment manuals to define preservation methods rather than applying one storage treatment to the whole factory.

How Seasonal Shutdown Differs from A Routine Stop

A routine stop leaves equipment close to its next operating condition. An off-season shutdown may involve weeks or months of inactivity, maintenance access, disconnected services, and changes in staffing.

Planning Item	Routine Stop	Seasonal Shutdown
Expected duration	Short and relatively predictable	Longer, sometimes dependent on crop availability
Equipment condition	Prepared for the next scheduled run	Prepared for storage and controlled maintenance
Inspection	Checks associated with normal operation	Assigned inspections during the idle period
Repairs	Limited work within a production schedule	Planned overhaul, parts replacement, or modification
Restart	Established operating procedure	Condition review and staged readiness approval

Define the shutdown boundary before the final production day:

• List the machines, product circuits, and utility interfaces included.
• Identify systems that remain active, such as required building services.
• Record the expected idle period and environmental conditions.
• Assign production, maintenance, quality, and contractor responsibilities.
• Set a target date for completing repairs before incoming fruit arrives.

The broader operational pressures are discussed in Vortech’s tomato processing plant challenges guide.

Complete Final Cleaning And Verify The Results

Do the final product removal and cleaning while the line is still in a condition that supports its approved cleaning procedure. Record the result before dismantling equipment or changing its configuration.

Cleaning Task	Evidence to Keep
Recover or remove remaining product	Product disposition and affected equipment
Execute the approved cleaning sequence	Circuit, cleaning conditions, operator, and completion record
Check accessible product-contact areas	Findings from the defined inspection points
Confirm the final rinse endpoint	Results against the site’s approved acceptance method
Investigate persistent deposits	Location, photographs, corrective work, and recheck
Establish the preservation condition	Equipment-specific method and responsible person

Check Areas That Can Retain Product

• Pump housings, valve cavities, and low points in pipework.
• Pulper screens and places where skins or seeds accumulate.
• Heat-transfer surfaces and evaporator discharge sections.
• Mixing-tank outlets, scraper assemblies, and sampling points.
• Filling nozzles and components excluded from a particular CIP circuit.

Use the documented cleaning parameters suitable for the installed materials and equipment. A completed cycle record does not establish that every disconnected or manually cleaned component was included.

For evaporator deposits, see Vortech’s scaling and fouling guide. Treat unresolved deposits as recorded work, not as a problem to rediscover at start-up.

Cleaning at season-end does not establish hygiene readiness months later. Include the required pre-production cleaning and hygiene verification in the restart plan.

Prepare Each Equipment Group for Storage

Tomato processing equipment preservation depends on construction, seals, lubricants, controls, and the storage environment. Drainage and drying may suit some circuits; other components require a different manufacturer-defined lay-up condition.

Equipment Group	Preservation Review	Restart Requirement to Record
Washers, sorters, and conveyors	Remove debris; inspect belts, chains, and approved lubrication needs	Reassembly, guarding, tension, and operating checks
Crushers and pulpers	Clean screens and internal components; identify removed parts	Screen condition, fastening, clearances, and rotation checks
Tanks and product piping	Confirm drainage or other specified storage condition; protect openings	Remove temporary closures and verify the intended circuit
Pumps and valves	Follow seal, elastomer, lubrication, and storage instructions	Confirm assembly and permissible conditions before operation
Preheaters and evaporators	Review product and service circuits separately	Confirm cleaning, leaks, instruments, and service readiness
Filling equipment	Protect product-contact parts and format components	Refit parts, verify settings, and test the package
Motors and controls	Review humidity protection and manufacturer storage requirements	Authorised electrical and control checks

Label Temporary Changes So They Can Be Reversed

• Tag disconnected hoses, removed instruments, and stored format parts.
• Identify temporary covers, blanks, and preservation materials.
• Keep removed parts with their equipment references and storage locations.
• Record any maintenance-related software or setpoint changes.
• Add every restoration task to the restart work list.

Do not coat product-contact surfaces with unspecified protective materials. Record any approved preservation treatment and the procedure for removing it before food production.

Pressure equipment, boilers, and specialist utility systems need their own lay-up procedures. Include their readiness in the programme without assuming the product-line checklist covers their maintenance requirements.

Inspect Wear Parts And Schedule Off-Season Repairs

Use operating records from the completed campaign to decide what needs attention. Recurring leakage, vibration, filling variation, or declining heat-transfer performance should lead to an inspection task with a clear completion requirement.

Component or System	Review Before Ordering Parts
Pulper screens and crushing components	Wear, damage, required geometry, and material specification
Pump seals and valve elastomers	Installed variant, compatibility, and failure history
Scrapers and agitators	Condition, attachment, clearances, and supplier limits
Bearings and drive components	Inspection findings, lubrication history, and confirmed part identity
Instruments	Calibration status, damage, and replacement configuration
Filling and sealing components	Format requirements, wear, and package-test results

Prioritise work by production consequence, lead time, and repair access. Separate confirmed replacements from items that still need inspection; otherwise a large parts order can leave the actual fault unresolved.

For each repair, record the work performed, parts installed, checks completed, and remaining restrictions. Equipment replacement decisions can also draw on Vortech’s new and used line comparison.

Build A Preservation Register And Inspection Schedule

A preservation register should describe each machine’s actual condition. “Shut down” is insufficient when one unit is dismantled, another is isolated, and a third remains connected to a service.

Register Field	Information Required
Equipment identity	Tag, description, manufacturer, and applicable manual
Cleaning status	Completion date, findings, and verification record
Preservation method	Approved condition, actions taken, and environmental requirements
Isolation and access	Controlled status and responsible personnel
Removed components	Part identity, quantity, and storage location
Open work	Defects, repair order, parts requirement, and completion date
Inspection plan	Tasks, interval, owner, and escalation criteria
Restoration	Steps and evidence required before release

Set inspection intervals from the manuals, environment, and equipment condition. Increase attention after water ingress, building leaks, unexpected humidity, or disturbance by contractors.

Inspection should have a defined response. If a cover is damaged or moisture appears, record the event, assess affected equipment, correct the cause, and update its preservation status.

Monitor The Line during The Idle Period

The off-season inspection route should be short enough to complete consistently and specific enough to identify a changed condition.

• Check for leaks, condensation, corrosion, damaged covers, and pest activity.
• Confirm stored parts remain labelled and protected.
• Check that temporary closures and service arrangements remain as recorded.
• Review authorised maintenance access and changes to the equipment.
• Follow prescribed checks for lubrication or movement of components where applicable.
• Record findings, corrective actions, and the next inspection date.

Keep idle-period inspections separate from permission to energise machinery. Any powered test requires the approved work procedure, appropriate operating conditions, and control of the surrounding area.

Restart in Stages before The Next Tomato Campaign

Begin the restart while there is still time to correct defects without delaying fruit processing. Passing one stage should release the next defined activity, rather than authorising unrestricted production.

Stage	Required Checks	Release Evidence
1. Condition review	Preservation history, inspections, and outstanding work	Updated equipment-status list
2. Mechanical restoration	Reassembly, temporary materials removed, guards and service access restored	Completed restoration and maintenance records
3. Utility readiness	Required electricity, water, steam, air, drainage, and other services	Confirmed requirements at equipment interfaces
4. Controls and instrumentation	Configuration, calibration, alarms, and approved interlock checks	Recorded results and closed defects
5. Cleaning and hygiene	Required cleaning, sanitising where specified, and verification	Quality release for the intended operation
6. Functional trials	Permitted test medium, sequence, leaks, flow, and equipment response	Approved trial record
7. Product trial	Representative feed, process performance, and package checks	Acceptance against agreed production criteria

Use Test Conditions Appropriate to Each Machine

• Confirm allowable test conditions with the equipment instructions.
• Do not assume pumps, seals, or product-contact assemblies can run dry.
• Review the trial sequence across connected machines before starting.
• Record changes made during testing and repeat affected checks.
• Reconcile product and cleaning requirements after the trial.

Hold equipment with unresolved faults outside the released operating scope. Record who approves restoration of energy sources and how that approval connects to maintenance close-out.

Confirm Production Readiness before Receiving Fruit

• Preservation materials and temporary arrangements have been accounted for.
• Repairs are complete, or restrictions have an approved resolution.
• Utilities, controls, instruments, and product circuits have been checked.
• Cleaning and hygiene evidence covers the restored configuration.
• Product trials meet the agreed process and packaging requirements.
• Operators have current procedures and understand any modifications.
• Parts, service contacts, and the start-up response plan are available.

For a seasonal inspection, repair, or upgrade enquiry, send Vortech your equipment list, previous-season faults, planned restart date, and proposed changes through the project enquiry page. Include existing manuals and maintenance records so the review can focus on the installed line.
