Embodiment Construction
[0074] See attached figure 1 . The vortex impinging flow microwave heating vacuum flash dehydration concentrator of the present invention, the main body 21 is a cylindrical tank body, and four 75KW microwave generators and wave guides 3, one wet cyclone separator 2 and vacuum pump exhaust pipe 14 are installed on the top; A shielding cover 4 is also installed on the upper part of the tank body to protect the microwave launcher and waveguide; in the middle and upper part of the tank body, 4 feeding pipes and vortex jet nozzles (6, 7, 8) are installed, Under the action of the high-pressure mud pump, the four nozzles shoot each other at a high speed of 10-15m / s, forming two suspended strong impact reaction areas where the droplets are continuously rotating, diffusing, and evaporating; in the middle and lower part of the tank, there is a Rod-type rotary evaporating bed 13 made of PTFE, the material liquid forms a semi-circular evaporation facade on the rotating rod, and countles...

The invention discloses an impact flow microwave heating vacuum flashing dehydration thickener, which is a vacuum flasher integrally. The top is provided with a microwave generator, the middle is provided with an impact flow device, the lower middle part is provided with a rod type rotary evaporation bed, and the lower part is provided with a juice and sauce storage kettle and a stirrer; and fruit and vegetable primary pulp is jetted through a plurality of groups of eddy impact flow, passes through the rod type rotary evaporation bed and enters the storage kettle, and free water and bound water are simultaneously heated under the combined action of microwave heating and vacuum flashing evaporation, and are evaporated at an extra-large-phase interface in various forms such as drops, films,curtains and boiling so as to greatly improve the dehydration thickening efficiency. The impact flow microwave heating vacuum flashing dehydration thickener radically solves outstanding problems of high-carbon emission, high pollution, high energy consumption, low efficiency and low benefit due to a fact that the traditional juice and sauce thickening process is equipped with a large boiler, a steam heat-exchange tower, a tank and a pipe network, realizes environmental friendliness, energy conservation, emission reduction, high quality and high efficiency, can be widely applied to a fruit andvegetable juice and sauce thickening process in the food industry, and also can be applied to a dehydration process in the medicine and chemical industries.
Description
(1) Technical field: [0001] The invention relates to the field of fruit juice and sauce processing machinery in the food industry. It is used for concentrating the puree of all fruits and vegetables such as tomatoes, apples, strawberries, mangoes, hawthorns, peaches, plums, dates, apricots, plums, etc., to make concentrated juices, sauces or fruit flavors. It can also be used in the dehydration and concentration process of slurry in light industry, chemical industry, pharmaceutical and other industries. (two), background technology: [0002] 1. Current similar product categories [0003] At present, the main types of fruit juice and sauce processing and concentration equipment commonly used in China are: three-effect four-stage mixed-flow low-temperature vacuum concentration device, three-effect vacuum concentration evaporator, four-effect five-stage falling film evaporation device, multi-effect multi-pass There are no less than ten types of evaporation and concentration de...
