Clean vegetable processing line operation points

Clean dishes are also called freshly sterilized vegetables. A product made from vacuum-packed freshly picked vegetables, processed (such as removing inedible parts, cuts, etc.), washing, and disinfecting, in a sterile environment. The following is just an example.

(1) Product Features

The vegetables are fresh, convenient and hygienic, and can be directly cooked in the pan. The refrigerator can be kept fresh for up to 1 week.

(2) Main raw materials

Fresh peppers, garlic, rape, carrots, celery, cauliflower, etc., citric acid.

(3) Process flow of clean vegetable processing production line

Fresh vegetables → Finishing (removing the inedible part) → Washing → Pre-cooking → Cooling → Cutting, block → Washing → Over-scale → Bagging → Sealing → Finished product (storage in the refrigerator)

Note: Over-weighing, bagging, and sealing are performed in the aseptic operation room.

(4) Description of the operation points of the clean vegetable processing production line

1 pre-cooked: dish: water = 1:3, and added 0.5% citric acid and stirred constantly. For tubers and rhizomes, such as carrots and cauliflower, the pre-cooking temperature is 95-100 ° C for 45-50 seconds. For stems and vegetables containing more chlorophyll, such as celery, garlic, rape, etc., pre-cooking temperature of 100 ° C, time 10 ~ 20 seconds, requires water to be added after boiling. Pre-cooking should be thorough, and try to maintain its flavor, color, and tissue state, especially not soft or coarse fibrous.

2 Cooling: It is cold-permeable with flowing water or cold air, and it is easy to change color when it is not cold.

3 Seal: When the vacuum is close to 0.1 MPa, the seal should be tight and flat.

4 sterile room control: air filter is used to filter the air, and must be disinfected with UV light for 30 minutes before work.

5 Finished product preservation: It is better to keep it at low temperature and avoid light.

(5) Product quality indicators

Stored in the refrigerator for 1 week, it is still very fresh, the degree of deterioration is very low, and the food quality is good.
