Product routes
- juice
- vegetable blend base
Incoming material and preparation
Will the contracted ingredient contain stalks only or include leaves, and what soil or fibrous trim must be removed before extraction?
Which feed length and preparation method work with the chosen equipment, and what residual fibre, sediment and celery flavour intensity must the buyer approve?
Define incoming state, variety, maturity, accepted defects and supply interruptions in the purchasing brief. A proposed line should be demonstrated with representative commercial lots rather than a single ideal sample.
Inspect incoming celery
Identify accepted stalk condition and remove unsuitable material.
State whether leaves and basal portions are included or removed in the purchased feed specification.
- Equipment duty: Receiving conveyor and inspection table
Separate soil and debris
Clean the intended edible fraction before cutting.
Keep dirty wash water and basal trim outside the clean extraction path.
- Equipment duty: Vegetable washer and controlled rinse
Trim to the product brief
Prepare the defined stalk and leaf fraction.
A stalk-only and a whole-edible-plant feed should not be compared as though they were the same material.
- Equipment duty: Trimming and inspection station
Control cutting
Present a repeatable fibrous feed to pressing.
Record the prepared feed condition; cutting can change separation behaviour and the suspended solids entering the juice.
- Equipment duty: Chopper or shredder
Press and collect
Separate liquid from the fibrous fraction.
Compare juice quality and rejected fibre as well as gross liquid recovery.
- Equipment duty: Vegetable-compatible juice press
Finish the juice
Meet the intended pulp and particle requirement.
Further clarification or a formulated blend is a separately developed route.
- Equipment duty: Coarse screen and covered buffer
Specify preservation around the actual product
Confirm the measured product composition, particulate load and intended storage chain before the treatment and filling arrangement is selected.
The pressed stalk juice route needs its own validated process. A drawing, a heat-exchanger name or a successful extraction trial does not establish a safe treatment schedule or a finished shelf-life claim.
- Equipment duty: Selected treatment unit, controlled transfer and process instruments
Fill, identify and verify the packed ingredient
Match the approved ingredient to the selected package and handling conditions. Record the production lot and the conditions required by its defined distribution route.
The filling boundary belongs in the project specification: container format, product-contact interface, filling hygiene, storage and the downstream user’s receiving requirements must agree before commercial acceptance.
- Equipment duty: Compatible filler, packaging interface and lot-identification station
Quality checks along the process
Assess soil or grit, fibrous particles, flavour and sediment with the actual feed preparation recorded. Do not use a vendor’s trial output as a performance guarantee.
Define the sampling location, sample preparation, measurement method and acceptable variation. Retain traceable comparisons through the intended downstream route; a favourable immediate sample is not proof of storage stability.
Equipment modules and selection
| Equipment module | Process role | Selection basis |
|---|---|---|
| Receiving conveyor and inspection table | Control the incoming-material presentation before preparation. | Check actual lot condition, peak arrivals and the accepted size range. Provide a sample/reject point that can be operated without obstructing feed to the next machine. |
| Trimming and inspection station | Soil removal and texture development. | Preparation, particle size and any conditioning step should be evaluated for the actual vegetable and product. Do not borrow a fruit-juice preservation schedule for a vegetable formulation. |
| Chopper or shredder | Create the agreed intermediate condition for downstream equipment. | Agree an acceptance sample, a measurable particle or separation target and a reject-handling method. Select contact parts and access arrangements after trials with representative material. |
| Product buffer and transfer system | Connect preparation, treatment and filling without assuming all sections run at the same rate. | Record viscosity, particle character, temperature envelope and expected stoppages. Confirm drainability, sampling points and how unaccepted or interrupted product is identified and handled. |
| Preservation, packaging and cleaning interfaces | Complete the declared process boundary. | The quoted scope should identify included instruments, services, containers, hygienic connections and validation responsibilities. An item list without these interfaces is not a complete line specification. |
Packaging and storage interfaces
Specify whether the pressed stalk juice is supplied as a chilled, frozen, otherwise treated or aseptically handled ingredient, as applicable to the developed product. Package material, closure, fill conditions and distribution are a connected system. Any claimed ambient stability or shelf life requires product- and package-specific validation; the process introduction does not set treatment temperatures or holding times.
Product and residue streams
Collect basal trim, damaged material and fibrous press cake separately. A proposed fibre co-product requires an independent acceptance and handling plan.
Cleaning circuits and physical access
Long fibres can bridge contact areas and remain around screens or press discharge. Provide access for inspection and separate the dirty washing zone from the juice circuit.
Assign cleaning responsibilities to the open preparation zone and the closed product circuit separately. Confirm which parts require removal or inspection and how cleaning effectiveness will be demonstrated with the actual product soil.
Inputs for the engineering brief
- Compare the declared stalk/leaf composition and controlled cut condition, checking the juice and fibrous rejects together.
- Provide the intended finished-product specification, representative raw-material samples, daily operating pattern and seasonal peak load.
- Identify available utilities, factory layout, drainage, reject collection and the exact inlet/outlet conditions of equipment supplied by others.
- Agree trial acceptance criteria and define the preservation, filling, cleaning and commissioning responsibilities before finalising the equipment scope.
Compare the preparation and concentration basis
A fresh-tomato paste line connects receiving and break treatment with skin/seed separation and a specified concentration duty. Other fruit and vegetable products can need different preparation and texture controls, and a concentrate is not simply any puree put through an evaporator.
Compare the tomato pulp-finishing and evaporation duties below with the product stream described on this page. The raw-material specification, solids measurement, viscosity and preservation/package interface must define the actual configuration.
Sources and processing scope
The references support these material and processing considerations. The actual equipment, process conditions, preservation method and packaging interface follow the specified raw material and finished product.

Questions about this equipment and process
Why record chopping before a celery press trial?
The press receives the prepared material, not the original stalk description. A documented cut condition allows a separation result to be compared with normal production and later trials.
Can celery and spinach results be treated as identical?
No. Both can be investigated as vegetable feeds, but their structure and selected edible fraction differ. Each actual material and product target needs its own demonstration.
What should a useful celery trial establish?
Compare the declared stalk/leaf composition and controlled cut condition, checking the juice and fibrous rejects together. Record incoming material, accepted feed, finished ingredient and each reject stream separately. Keep settings, samples and analytical methods with the trial record so the result can be compared with subsequent seasonal lots.
