Blanching machine

Abstract

The invention belongs to the field of food processing machinery, and particularly relates to a blanching machine. The blanching machine comprises a housing; a material inlet and a material outlet areformed in the two sides of the housing; a belt conveyor, a motor, spray heads and a water heating device are arranged in the housing; a hopper is arranged above the material inlet in the housing; a pair of horizontal first rollers are arranged between the lower part of the material inlet and the belt conveyor; a gap is formed between the two first rollers; the first rollers are driven by the motor; groups of openable doors are arranged on the top surface of the housing; a cross beam is arranged between each group of doors; a lifting device is arranged on the cross beam; a second roller is arranged below the lifting device; a row of spray heads are arranged below the belt conveyor; an opening is formed in the side wall below the material inlet in the housing; a material residue filter screen drawer is arranged in the opening; a temperature sensor and a controller are arranged in the housing; the controller is connected with the motor, the belt conveyor, a hydraulic rod, the lifting device and the temperature sensor. The blanching machine has comprehensive functions and can produce high-quality blanching products.

Description

technical field [0001] The invention belongs to the field of food processing machinery, in particular to a blanching machine. Background technique [0002] The blanching machine is mainly used for blanching and finishing fruit, root vegetables, carrots, asparagus, mushrooms, fruit slices and other fragile products. It is an indispensable blanching equipment for quick freezing, dehydration, freeze drying and other pretreatment processing. The blanching treatment equipment often required in the medium color protection process, after blanching, stops the activity of enzymes in fruits and vegetables, so as to maintain the unique fresh color of fruits and vegetables, emit green odor of vegetables and retain fragrance, improve the softness of cells, and benefit The evaporation of water lays a good foundation for the technological requirements of the next drying and dehydration process. [0003] There are three types of blanching machines: belt blanching machine, belt superheated ...

AI Technical Summary

Problems solved by technology

During the daily use of the blanching machine, there are various types of blanching, and the following problems often exist in daily blanching: First, during the blanching process of leafy vegetables, some leafy vegetables will float on the On the surface of the water body, the blanching effect is not good. Secondly, in the process of blanching some thinner leafy vegetables or rhizome fruits with higher starch content, it is easy to produce various debris. These debris are in the blanching water. Floating, which in turn affects the quality of the finished product. Finally, due to blanching opportunities for blanching various products, the blanching and cooling temperatures and times of different products are not exactly the same. Only different blanching temperatures and Blanching time, in order to get better products
