Description

Technical Field

[0001] This utility model belongs to the field of fruit and vegetable deep processing technology, specifically relating to an NFC quick-frozen fruit and vegetable juice / pulp engineering production equipment system. Background Technology

[0002] Non-concentrated (NFC) frozen fruit and vegetable juice / pulp is a type of juice / pulp base made from fruits and vegetables through washing, pulping, homogenization, sterilization, and packaging. It has not undergone concentration or reduction and does not contain any other exogenous substances. It has high flavor quality, antioxidant activity, and rich nutrients such as vitamin C, and has experienced rapid development and widespread popularity.

[0003] Currently, NFC (Not From Concentrate) quick-freezing technology for processing fruit and vegetable juices / pulps is limited and lacks innovative research, significantly restricting its application in high-quality food processing. For example, pulpers that use mechanical friction for direct crushing often generate a large amount of heat, causing the pulp temperature to rise to 45-75℃. This hot pulping process easily leads to the loss of flavor compounds and nutrients in the fruit and vegetable juices / pulps, reducing sensory quality. Furthermore, the increased temperature causes softening of the fruit pulp, and some pulp may stick to the inside of the pulper, reducing pulping efficiency. In addition, traditional quick-freezing and heat sterilization methods can easily cause denaturation of flavor components in fruit and vegetable juices / pulps, and unhomogenized fruit and vegetable juices / pulps are prone to pulp sedimentation during production and storage, further reducing the sensory quality of the product. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an NFC quick-frozen fruit and vegetable juice / pulp engineering production equipment system to solve the problems existing in traditional hot pulping equipment.

[0005] In view of the shortcomings of the existing technology, the inventors have conducted extensive experiments and research and made continuous improvements, and finally obtained the following technical solution: an NFC quick-frozen fruit and vegetable juice / pulp engineering production equipment system, including an ultrasonic soaking and cleaning structure, a refrigeration pulping machine, a high-pressure homogenizer, a vacuum degassing machine, a filling machine, a sterilization device and a quick-freezing device; The ultrasonic immersion cleaning structure is equipped with a fruit and vegetable feeding channel and a discharging channel.

The fruit and vegetable feeding channel is located at the top of the soaking tank, and the discharging channel is located at the lower part of the side wall of the soaking tank.

[0007] A further preferred embodiment is that the fruit and vegetable feeding channel is equipped with a screw feeder and a control motor connected to the screw feeder.

[0008] A further preferred embodiment is that the refrigerated pulping machine includes a pulping tank, a drive motor disposed on the top of the pulping tank, pulping blades disposed inside the pulping tank and connected to the drive motor, and a refrigeration system disposed on the pulping tank.

[0009] A further preferred embodiment is that the refrigeration system includes a PLC controller, a refrigeration compressor, an evaporator, and a condenser connected to the PLC controller, and a temperature sensor is fixedly installed inside the pulping tank, the temperature sensor being connected to the PLC controller.

[0012] A further preferred embodiment is that a pressure sensor and a PLC regulator are installed inside the homogenizing tank.

[0013] A further preferred embodiment is that the filling machine is a fully automatic filling and capping integrated machine.

[0014] A further preferred embodiment is that the sterilization device is an ultra-high pressure non-thermal sterilizer.

[0015] Compared with existing engineered production equipment for quick-frozen fruit and vegetable juice / pulp, the engineered production equipment system of this utility model includes an ultrasonic soaking and cleaning structure, a refrigeration pulping machine, and a high-pressure homogenizer, etc., and has the following beneficial effects: (1) Through the ultrasonic soaking cleaning structure, physical and chemical cleaning agents can be used to clean fruits and vegetables, which can significantly reduce the total number of colonies on the surface of fruits and vegetables, especially the total number of molds on the surface of fruits and vegetables.

[0016] (2) Using a refrigerated pulping machine for refrigeration pulping can avoid the temperature rise of the pulp during the pulping process, thus preserving heat-sensitive substances.

In practical applications, the screw feeder and control motor are evenly supported and connected within the fruit and vegetable channel, and the supports do not affect the normal feeding and conveying operation of the fruits and vegetables.

It is a conventional structure based on existing technology, simply applying it in a basic way.

[0031] Its usage is as follows: Taking mango as an example, the mango is treated with ultrasound and cleaning agent in an ultrasonic soaking and cleaning structure. The clean mango is then sent to a peeling and pitting machine for peeling and pitting, and then sent to a refrigeration pulping machine for freezing and pulping. The resulting coarse mango pulp is then sent to a high-pressure homogenizer for refining and pulping to obtain refined mango juice / pulp. The mango juice / pulp is then sent to a vacuum degasser for degassing, and then filled by a filling machine.
