Description

TECHNICAL FIELD

[0001] The present application belongs to the field of fruit by-product processing equipment manufacturing, and particularly relates to a pomace processing system and method. BACKGROUND

[0002] Pomace, as a by-product generated after the processing of agricultural products (such as juice extraction or brewing of apples, citrus fruits, grapes, etc.), is rich in cellulose (accounting for 15%-30%), hemicellulose, pectin (content up to 10%-25%), organic acids (such as malic acid, citric acid), and minerals such as potassium and calcium, and has significant biomass resource potential. However, there are double dilemmas in the traditional processing method. During the peak season of fruit processing, a single production line can produce tens of tons of pomace per day. If it is directly piled up without processing, its high water content (>80%) and perishable characteristics will lead to rapid reproduction of microorganisms, and within 48 hours, it will produce foul-smelling gases (such as hydrogen sulfide and ammonia) and seep acidic wastewater, polluting the soil and groundwater, and attracting mosquitoes and flies to breed, threatening the surrounding ecology and public health. For example, the utility model with publication number CN114642265A discloses a pomace drying treatment equipment, which belongs to the field of fruit by-product processing equipment manufacturing. The pomace drying treatment equipment comprises a shell, a microwave chamber, an air compressor, a heater, and a grinding chamber.

The exhaust port is located above the filter screen and at the bottom of the microwave chamber. The heater is an electric heater, and a plurality of vertically arranged flow guide pipes are formed in the heater. A grinder is arranged in the grinding chamber.

[0003] Although the above-mentioned device can heat the pomace by microwaves, remove the excess moisture by blowing, and grind the pomace again to prevent clumping, the heating and crushing links of the device are arranged in separate chambers, and the material needs to be transferred through a pipeline, which increases the overall volume of the equipment.
