DCGSYL-6 fruit and vegetable vacuum pre-cooling fresh-keeping machine
DCGSYL-6 fruit and vegetable vacuum pre-cooling and preservation machine is a pre-cooling and preservation processing equipment for fruits and vegetables and other foods. It has the advantages of rapid pre-cooling, maintaining food quality and extending the shelf life.
1. Principle: The principle of DCGSYL-6 fruit and vegetable vacuum pre-cooling and preservation machine is to use a vacuum pump to extract the air
in the vacuum chamber to make it in a vacuum state. At the same time, the heater pre-cools and preserves the materials in the vacuum chamber.
In this vacuum environment, the moisture in the material will evaporate quickly, causing the temperature of the material to drop,
achieving the purpose of pre-cooling and preservation.
2. Function: The main function of DCGSYL-6 fruit and vegetable vacuum pre-cooling and preservation machine is to quickly pre-cool fruits and
vegetables and other foods to reduce the moisture content in the material, lower the temperature of the material, extend the shelf life,
and at the same time, it can also perform fresh-keeping processing to improve food quality. and taste.
3. Advantages: The advantages of DCGSYL-6 fruit and vegetable vacuum pre-cooling machine include:
(1) Rapid pre-cooling: It can reduce the temperature of the material to a suitable range in a short time, reduce the moisture content in the material,
and improve the quality and taste.
(2) Preservation treatment: In a vacuum environment, it can inhibit the growth and reproduction of microorganisms in fruits and vegetables
and other foods, and extend the shelf life.
(3) Energy saving and environmental protection: Vacuum pre-cooling treatment can reduce the moisture content in the material,
thereby reducing energy consumption and waste water emissions during the cooling process.
4. Disadvantages: The disadvantages of DCGSYL-6 fruit and vegetable vacuum pre-cooling machine include:
(1) Equipment costs are high: Vacuum precooling treatment requires the use of vacuum pumps, vacuum pipelines and other equipment,
and the equipment costs are relatively high.
(2) High operating requirements: Vacuum pre-cooling treatment needs to be carried out in a vacuum state,
which requires high operating requirements and requires proficiency in equipment operation and maintenance technology.
5. Scope of application: DCGSYL-6 fruit and vegetable vacuum pre-cooling and preservation machine is widely used in fruit and vegetable,
food, pharmaceutical and other industries. It can quickly and effectively pre-cool and preserve various materials, extend the shelf life,
and improve quality and taste.
6. System: DCGSYL-6 fruit and vegetable vacuum pre-cooling and preservation machine is mainly composed of vacuum system, cooling system,
control system and safety system. Among them, the vacuum system consists of a vacuum pump, a vacuum pipeline, a vacuum valve, etc.,
and is used to extract the air from the vacuum chamber to achieve a vacuum environment. The cooling system consists of a cooler, cooling pipes,
cooling valves, etc., and is used to cool and preserve materials. The control system consists of PLC controller, temperature sensor and control button, etc.,
and is used to control the operation and parameter monitoring of the equipment. The safety system consists of safety valves, explosion-proof valves
and alarms, etc., and is used to protect the safety of equipment and personnel.
7. Equipment type: DCGSYL-6 fruit and vegetable vacuum pre-cooling and preservation machine is a kind of vacuum pre-cooling
and preservation equipment, which is mainly used for pre-cooling and preservation in fruits and vegetables, food, medicine and other industries.
8. Production process: The production process of DCGSYL-6 fruit and vegetable vacuum pre-cooling and preservation machine mainly includes
the following steps:
(3) Preservation: After pre-cooling is completed, the materials continue to stay in the vacuum chamber.
By adjusting parameters such as vacuum degree and temperature, the materials are placed in a low-oxygen, low-temperature,
and low-humidity environment, thereby extending the preservation period of the materials.
9. Equipment parameters: DCGSYL-6 fruit and vegetable vacuum pre-cooling and preservation machine has a processing capacity of 600-1000kg/h,
a vacuum degree of 0.09MPa, a cooling temperature of -8°C, and a preservation time of 7-15 days.
10. Structure: DCGSYL-6 fruit and vegetable vacuum pre-cooling and preservation machine is mainly composed of vacuum system, cooling system,
control system and safety system. Among them, the vacuum system consists of a vacuum pump, a vacuum pipeline, a vacuum valve, etc.,
and is used to extract the air from the vacuum chamber to achieve a vacuum environment. The cooling system consists of a cooler, cooling pipes,

and control button, etc., and is used to control the operation and parameter monitoring of the equipment.
The safety system consists of safety valves, explosion-proof valves and alarms, etc., and is used to protect the safety of equipment and personnel.
11. Control system: The control system of DCGSYL-6 fruit and vegetable vacuum pre-cooling and preservation machine adopts PLC controller,
which can realize functions such as automatic control, parameter monitoring and fault alarm. At the same time,
the equipment is also equipped with temperature sensors and control buttons for easy operation and adjustment.
(1) Material preparation: Clean, classify and package fruits and vegetables that need to be pre-cooled and kept fresh.
(2) Pre-cooling: Put the material into the vacuum chamber, and pump out the air in the vacuum chamber through a vacuum pump
to keep it in a vacuum state. At the same time, the heater pre-cools the materials in the vacuum chamber,
causing the moisture in the materials to evaporate quickly, thereby lowering the temperature of the materials to achieve the purpose of pre-cooling.
