Hot-Press Trial and Acceptance Record

Oil recovery is not a fixed model value. For 300/325 hot-press projects, compare repeated trials on the same raw-material lot and record the heating step instead of using a generic yield table.

Trial field	Record before acceptance
Raw material	Variety, supplier lot, cleaned feed mass, impurity level and measured moisture
Preparation	Crushing size, roasting or conditioning temperature, holding time and feed temperature
Press cycle	Basket size, actual load, pressure sequence, holding time, unloading time and complete cycle time
Oil result	Net oil after the agreed settling or filtration step, with container tare removed
Cake result	Cake mass and residual oil measured by the agreed laboratory method
Comparison basis	At least two repeatable runs using the same lot, calculation formula and measuring instruments

Feed-basis yield and recovery relative to measured oil content are different figures. The quotation and acceptance document should state which calculation is used; no percentage is guaranteed without a representative witnessed trial.

Pressing Barrel Selection Guide:

• Standard barrel specifications:
  • Diameter: 390mm
  • Length: 800mm
  • Volume: 95.6 liters (can hold about 100kg of crushed material, continuously compacted)
  • Material and barrel compatibility must be verified for the intended hot-press route with representative material; barrel dimensions alone do not establish suitability.
• 300mm diameter is recommended as sesame-specific barrel
  • Suitable for sesame and other small particle oil materials
  • Verify small-particle loading, drainage, complete cycle time and cake residual oil by trial.
  • Volume: 56 liters
• 480mm /560mm /630mm diameter is recommended for oil materials requiring long pressing time
  • Suitable for oil materials requiring long pressing time
  • Confirm load, pressure-holding time and the complete cycle with the selected barrel.
  • Volume: 145/197/249 liters
• A 2100 mm dual-barrel configuration may be quoted; confirm current manufacturability, dimensions, scope, and lead time in the signed offer. The 1200 mm single-barrel configuration shown here is also subject to order confirmation.

Pressing Material Guide:

• Partial oil material pressing process guidance as follows:
• Peanut (Recommended 300AC-390) + Peanut oil (rich aroma type) hot pressing process: Crush peanuts -> roast the peanut granules in a flat-bottom wok -> feed them into the hydraulic oil press barrel for pressing. + Record roasting temperature and time, feed temperature, oil color and aroma, net filtered oil and cake residual oil for the buyer's peanut lot. + Determine settling and filtration from the required finished-oil specification; no universal filtration exemption or unsupported brand reference is assumed. +
  • Sesame (Recommended 300AC-390)
    • Sesame hot-press route: clean and roast the sesame, then press it directly. Record the roast profile, oil temperature, net filtered oil, sediment and cake residual oil.
    • Determine settling and filtration from the required finished-oil specification; no universal filtration exemption or unsupported brand reference is assumed.
    • 
  • Tea seed (Recommended 300AC-390)
    • Tea seed oil hot pressing process: Tea seeds go through screening, cleaning, drying, crushing, steaming and stir-frying, then connected to hydraulic oil press barrel pressing.
    • Record the heating profile, oil temperature, color, sediment and the laboratory results required for the target tea-seed oil.
    • 
  • Walnut direct cold pressing (not a 300/325 recommendation)
    • For cleaning, optional low-temperature drying, crushing, and direct hydraulic cold pressing, evaluate the 355-500 series. Do not add default high-temperature conditioning between crushing and pressing.
    • 
  • Soybean (outside the default 300/325 recommendation)
    • The existing process media are retained as historical references only. Do not use them to select or accept a 300/325 line; soybean feasibility requires separate process, safety, and commercial review.
    • 
    • 
  • Flax/Flaxseed (Recommended 300AC-390)
    • Flax/Flaxseed hot pressing process: Flax seeds go through heating and stir-frying + grinding and stir-frying, then placed into hydraulic oil press barrel pressing.
    • 
    • Flaxseed hot-press trial: record crushing, heating profile, feed temperature, net filtered oil, sediment and cake residual oil before approving the route.
  • Rapeseed (Recommended 300AC-390)
    • Rapeseed oil hot pressing process: Rapeseeds go through cleaning, crushing, stir-frying and steaming processes, then placed into hydraulic oil press barrel pressing.
    • Record conditioning, press temperature, net filtered oil, cake residual oil, color and aroma against the agreed product specification.
    • 
  • Sunflower seed (Recommended 300AC-390) + Sunflower seed oil hot pressing process: Sunflower seeds go through cleaning, crushing, and stir-frying processes, then placed into hydraulic oil press barrel pressing.
  • Oil sludge (outside standard edible-oil and 300/325 selection scope)
    • Existing media are retained for record only and make no process, capacity, food-safety, or compliance claim.
    • 
  • Oil residue (outside the default 300/325 recommendation)
    • Existing media are retained for record only; a non-standard residue route requires separate material characterization, compliance review, and witnessed testing.
    • 
    • 
  • Meal residue (outside the default 300/325 recommendation)
    • Existing media are retained for record only; they are not a route, model, yield, or acceptance recommendation.
    • 
    • 
  • Waste bleaching clay (outside standard edible-oil and 300/325 selection scope)
    • Existing media are retained for record only. Recovery, disposal, safety, and environmental obligations require a separate compliance review and are not covered by this model recommendation.
    • 
    • 
  • Animal oil residue (outside standard edible-oil and 300/325 selection scope)
    • Existing media are retained for record only and are not a process, food-safety, or equipment-selection recommendation.
    • 
    • 
  • Medicinal residue (outside the default 300/325 recommendation)
    • Existing media are retained for record only; material safety, legal use, and process feasibility require separate review.

Items to Verify Before Purchase

1. Record actual batch load, complete cycle, shift hours, cleaning, changeover, utilities, and labor with the quoted barrel and hot-press route.
2. Confirm the supplied controls, sensors, filtration, heating equipment, and automation functions against the signed configuration list.
3. Treat oil quality, net filtered oil, cake residual oil, energy use, staffing, and maintenance as trial or operating measurements, not fixed model promises.

After-sales Service

• Warranty term, coverage, conditions, and exclusions follow the signed quotation and contract.
• Installation, commissioning, training, maintenance, remote support, travel, and spare-parts lead times apply only as specifically listed in the commercial scope.
• FAT and SAT protocols must state the test material, instruments, tolerances, pass criteria, corrective responsibility, witnesses, and sign-off.

Product Features

1. Confirm steel grade, welding, machining and inspection records for the ordered unit.
2. Treat pressure-control range and repeatability as acceptance items; they do not guarantee a fixed oil yield.
3. Verify each quoted automation function during FAT/SAT rather than assuming a labor reduction.
4. Establish maintenance work and operating cost from the delivered configuration and the buyer's duty cycle.

Application Range

• Small oil mills
• Family workshops
• Rural cooperatives
