The screw pre-cooking machine is also called screw blancher, it is suitable for continuous pre-cooking of vegetables with small shapes, so as to achieve the purpose of enzyme elimination and softening. It is stainless steel structure, spiral feeding, with a safety insulation layer. Continuous pre-cooking in a water bath, and the material is scraped out by a special turning hopper scraper. Pre-cooking temperature: ≤100℃. The equipment uses electric energy or steam as an energy source. It is designed and manufactured according to the principles of thermodynamics and various food requirements. It can blanch products of different specifications. The blanching time and temperature are automatically controlled, and the blanching process is simple and safe. Save water consumption and energy.

The machine is mainly used for enzyme deactivation, softening and color protection of dates, hawthorn, mango, coconut meat, beetroots, carrots and other fruits and vegetables.

The function of the pre-cooking machine is to steam and soften the washed fruits and adjust the speed to change the pre-cooking time to adapt to the softening of different fruits and vegetables.

• Destroy enzyme activity, prevent browning and fresh pectin,
• Soften the pulp tissue to increase the pulp yield rate and promote sugar liquid penetration.
• Dissolve the pectin in the pulp tissue to facilitate the processing of the next process.

1. The equipment is composed of a bleaching section and a cooling section. The heating source of this machine is steam heating, the temperature can be adjusted, with automatic control of steam inlet device and surface insulation. Minimize energy waste.
2. The transmission system of this machine adopts a speed-adjustable geared motor, and the spiral conveying speed is adjustable, and the blanching time can be between 3-15min.
3. The continuous pre-cooking machine is one of the raw material pretreatment equipment in fruit and vegetable processing. It can prevent browning, inhibit active enzymes and decompose the pectin in the fruit by cooking, and improve the pulping rate.
4. This machine can be used as a unit machine or connecting with other equipment in the production line; it is not only suitable for the processing technology of fruit juice and vegetable juice, but also suitable for the steaming and softening technology in the process of fruit jam.
5. According to the technological requirements of various materials, the machine can realize the adjustment of pre-cooking temperature and pre-cooking time, and is suitable for heating and cooking various fruit and vegetable raw materials;
6. Type spiral pre-cooking machine is mainly composed of the feed hopper, discharge hopper, inner cylinder, outer cylinder, screw, water inlet pipe, water outlet pipe, transmission part, frame and other parts.
7. During work, the material is added to the feed port and enters the screw pre-blancher. Under the action of the screw propeller, the material is discharged from the discharge port after reaching the temperature and time required by the process.
8. In addition, the transmission system of this machine is stepless speed regulation, which allows users to choose different pre-cooking time and speed requirements according to various materials in processing.
