Sweet potato storage pretreatment equipment and pretreatment method

Abstract

The invention relates to the technical field of sweet potato storage and discloses sweet potato storage pretreatment equipment and a pretreatment method. The sweet potato storage pretreatment equipment comprises an access door, a healing room and a cooling room with access doors oppositely arranged, wherein the end, departing from the cooling room, of the healing room is connected with a first air-supply fan, and a heat device is arranged between the outlet of the first air-supply fan and the healing room; and the end, departing from the healing room, of the cooling room is connected with a second air-supply fan. According to the sweet potato storage pretreatment equipment, sweet potatoes are subjected high-temperature short-time healing-cooling pretreatment after production and before storage, formation of sweet potato tuberous root healing tissues can be effectively accelerated by an environment-friendly pollution-free physical method, and the pretreatment time can be shortened, so that the aims of reducing rot and moisture loss of sweet potatoes during storage, ensuring the storage quality and prolonging the storage period can be achieved.

Description

technical field [0001] The invention relates to the technical field of sweet potato storage, in particular to a sweet potato storage pretreatment device and a pretreatment method. Background technique [0002] Sweet potato roots are large in size, rich in moisture, thin in skin and tender in flesh, and are susceptible to mechanical damage such as abrasions, punctures, cuts, bruises, and crushes during harvesting in the field, transportation, loading and unloading, and warehousing and storage. In order to reduce the postharvest loss of sweet potatoes and prevent the invasion of pathogens, postharvest sweet potatoes should be properly pretreated to remove surface soil-borne microorganisms and promote wound healing before storage, which will help improve the disease resistance of sweet potatoes and prolong storage Time limit, guaranteed storage quality. The pretreatment methods currently used in production practice mainly include three methods: callus pretreatment, cleaning pr...
