Problems solved by technology

[0004] However, the existing vacuum moisture reconditioning machine has insufficient moisture regain ability for sheet tobacco, and the permeability cannot meet the requirements. The moisture content at the outlet of the moisture conditioning machine is inconsistent, which affects the stability of cigarette quality. Adds a lot of moisture to the tobacco

Abstract

The invention discloses a method and system for controlling material vacuum moisture regain, and a moisture regain machine. The method includes: vacuumizing the chassis of the moisture regain machine with materials; and when the vacuum degree of the chassis meets the preset vacuum degree situation, control the water spray valve installed on the top of the cabinet to open the water spray operation; determine the upper temperature T of the cabinet u and the vaporization temperature T of water b ; at T u <T b In the case of +ΔT, control the steam injection valve installed on the top of the chassis to open the steam injection operation, and control the steam flow D of the steam injection valve q , to maintain T b <T u <T b +ΔT, wherein, ΔT is the preset temperature difference threshold; determine the moisture of the material; when the moisture of the material reaches the preset moisture threshold, control the water spray valve to stop the water spray operation and the The steam injection valve stops the steam injection operation.

Description

technical field [0001] The invention relates to the technical field of vacuum moisture regain, and more specifically, to a control method for vacuum moisture regain of materials, a control system for vacuum moisture regain of materials, and a moisture regain machine. Background technique [0002] As the first processing equipment of the cigarette production line, the main functions of the vacuum moisture reconditioning machine are: to loosen the cigarette bales; to remoisturize the laminar tobacco in the cigarette bales; it is expected that the moisture and temperature of the exported laminar cigarettes will be consistent with the given value; Increase the moisture content of the tobacco sheet to reduce the subsequent moisture increase. [0003] The existing vacuum dampening machine is composed of a box body, a vacuuming system, a material system and a control system, including working processes such as feeding, vacuuming, regaining moisture, maintaining pressure, breaking t...
