Abstract

The invention relates to the technical field of fruit and vegetable drying equipment, in particular to a steam and steam condensed water combined fruit and vegetable drying system. The fruit and vegetable drying system comprises a material transmission device and a preheating chamber, and is characterized by further comprising a high temperature steam drier and a high temperature condensed water drier, wherein the high temperature steam drier and the high temperature condensed water drier both are provided with a tail gas recovery system at upper parts; the upper part of the high temperature steam drier is communicated with a steam boiler through a general air supply pipe, the lower part of the high temperature steam drier is provided with a high temperature condensed water recovery pipe communicated with the upper part of the high temperature condensed water drier, and an intermediate material transmission device is arranged between the high temperature steam drier and the high temperature condensed water drier. The system avoids quality reduction caused by overheat of fruit and vegetable materials, reduces energy consumption for drying each unit material and improves the water removing rate of each unit energy consumption; besides, the system maintains the original quality of dry materials to the greatest extent, protects environment, saves energy, reduces cost and comprehensively uses energy resource.

Description

technical field

[0001] The invention relates to the technical field of fruit and vegetable drying equipment, in particular to a fruit and vegetable drying system using combined steam and condensed water. Background technique

[0002] At present, hot air drying is widely used in the existing drying of fruits and vegetables. The mechanism of this technology is consistent with that of other conventional materials. Its main feature is that hot air with appropriate temperature and air volume is used to promote the outward diffusion of moisture inside the material through capillary tubes. One of the heat supply systems of this technology uses a hot blast stove to directly supply the hot air required for drying materials, but the hot air in this system is mixed with the flue gas generated by fuel combustion, which will affect the quality of the product when used for drying fruits and vegetables, and consume a lot of energy. Renewable resources; the other is to use the boiler to sup...
