Grape Seed Oil Pressing Line

Grape seeds often arrive inside wet winery or juice pomace with skins, stems, pulp, and fermentation residue. The project must define whether the quoted input is wet pomace or separated dry seed; these are not interchangeable capacity bases.

Raw Material Boundary

Record pomace origin, time since pressing, skin and stem fraction, seed recovery basis, moisture, storage condition, and signs of mold or oxidation. Seed that has already been washed and dried must be quoted separately from wet pomace requiring recovery equipment.

Recommended Pretreatment

1. Separate seeds from skins, stems, pulp, and foreign material.
2. Wash only when the residue and wastewater plan require it.
3. Dry promptly under controlled conditions and cool before storage.
4. Screen again and remove metal or hard contaminants.
5. Crush the dry seed to a repeatable size immediately before pressing.

Pressing Route and Equipment

Start with a low-temperature hydraulic batch trial when the target is a specialty food or cosmetic oil. A gently conditioned comparison may be run on the same seed lot, but color, aroma, oxidation indicators, filtration behavior, and cake result must be recorded. The economics must include wet-pomace separation, drying, and seasonal operation rather than press capacity alone.

Equipment Entry Points

• Pretreatment equipment
• High-speed pulverizer
• Hydraulic oil press range
• 400 Series hydraulic oil press as a model entry for trial sizing
• Pneumatic filter press
• Filling equipment

Filtration and Finished-Oil Target

Specify settling and fine filtration, visible sediment, clarity, color, aroma, oxidation test method, and the package used to limit light and air. The sampling basis must state whether the evaluation is on crude oil, settled oil, or filtered oil.

Data Required for a Quotation

• Wet pomace or dry-seed sample, skin and stem residue, seed recovery basis, moisture, storage time, and mold or oxidation condition
• Capacity stated as wet pomace or dry seed, seasonal volume, daily drying hours, and pressing schedule
• Low-temperature or gently conditioned trial, intended food or cosmetic use, and oil-temperature recording requirement
• Settling, filtration, tank, package, and oxidation-test requirements
• Drying heat source, power, water and wastewater scope, floor space, destination, and delivery terms

Acceptance Records

Record wet-pomace and recovered dry-seed weights separately, impurity removal, moisture after drying, crush size, batch charge, cycle time, oil temperature, crude and filtered oil, and cake. After the agreed settling or filtration interval, document clarity, color, aroma, oxidation test results, and the exact sample and operating conditions used.
