Tunnel pipe type drying and fresh-keeping box

Abstract

The invention discloses a tunnel pipe type drying and fresh-keeping box, and particularly relates to a drying and fresh-keeping box for manufacturing dried long beans so as to improve the drying and fresh-keeping efficiency. The dried long beans are chewy and high in nutritional value, and the dried long beans are mellower and more delicious to eat and unique in taste. The resistance and immunityof the body can be enhanced by eating more dried long beans. However, the traditional preparation process of the dried long beans comprises the following steps: cooking fresh long beans, and airing the cooked long beans in the open air to be dry to obtain the dried long beans. The outdoor drying process link of the dried long beans is poor in sanitary condition, mice can come and spread diseases at night, and batch production is not facilitated. According to the tunnel pipe type drying and fresh-keeping box, airflow blown out of tunnel pipe airflow holes replaces the outdoor drying process, the dried long beans can be produced in batch, and the functions of mouse prevention and fresh keeping are achieved.

Description

technical field [0001] The invention relates to the technical field of food machinery and equipment, in particular to a drying and fresh-keeping box, in particular to a drying and fresh-keeping box for making dried beans, so as to improve air-drying and fresh-keeping efficiency. Background technique [0002] Dried beans are chewy, not only have high nutritional value, but also the dried beans taste more mellow and delicious, with a unique taste. Eating more dried beans is beneficial to the smooth production of various antibodies, which can enhance the body's resistance and immunity. However, the traditional production process of dried beans is to boil fresh fresh beans, put them into the open air to dry, and dry them to make dried beans. The open-air drying process of dried beans not only has poor sanitary conditions, but also rats will visit at night, spreading diseases, and it is not conducive to mass production. The present invention designs a tunnel-type air-drying fres...
