A processing and drying device and method for vegetables

Abstract

The invention provides a processing and drying device for vegetables, and relates to the technical field of processing of the vegetables. The drying device comprises a drying oven, wherein a heating cavity is arranged in the drying oven; a drying chamber is arranged at the upper end of the heating cavity; a partition board is arranged at the upper end of the drying chamber; a pressure valve is arranged at the upper end of the drying chamber; a control rod is arranged at the upper end of the pressure valve; a motor shaft is arranged on one side of a filter chamber; a water sucking pipeline is arranged on one side a filter rod; a dewatering box is arranged at the lower end of a limiting valve; a main transmission cavity pipe is arranged on the other side of the filter rod; a transporting door panel is arranged in a transporting region; and sliding rails are arranged on the surface of a sliding cavity. Through the adoption of the processing and drying device disclosed by the invention, the problems of most of vegetable drying devices in the current market are high in the hot-blast temperature, ingredients of organic substances, vitamin C and the like in the vegetables are greatly lostbecause of oxidization, the dried vegetables are poor in color and luster, the losses of nutrient components are serious, the grade is reduced, besides, the conventional vegetable drying devices do not reach the standard in the aspect of disinfection, the hygienic quality is not guaranteed, and time cannot be well controlled, so that the economic benefits are influenced are solved.

Description

technical field [0001] The invention relates to the technical field of vegetable processing, in particular to a processing and drying device and method for vegetables. Background technique [0002] At present, China's dehydrated vegetable exports account for more than half of the world's total, and the average annual growth rate is more than 20%. From 2007 to 2012, my country's dehydrated vegetable exports. At present, the price of freeze-dried vegetables in the international market is relatively high, and the average price is more than 5 times the price of hot-air-dried dehydrated vegetables, which has become the main direction for the development of dehydrated vegetables in my country. The development of freeze-dried food can further process the rich agricultural product resources to add value and earn foreign exchange through export. Dehydrated vegetables, also known as rehydrated vegetables, are a kind of dried vegetables made by washing and drying fresh vegetables to r...
