Description
Technical Field
The invention relates to a conditioning device, in particular to a vacuum conditioning machine with an automatic drainage device.
Background
The vacuum damping machine is the first procedure equipment for cigarette processing, and the materials (such as tobacco leaves) stored for a long time must be subjected to vacuum damping treatment before processing treatment, and the purpose of the vacuum damping machine is as follows: 1) The water content and the temperature of the tobacco leaves are properly improved, so that the tobacco leaves become soft, and the toughness is increased, so that the operation requirements of subsequent procedures are met; 2) Killing insects and sterilizing, wherein when the humidifying temperature is higher than 70 ℃, adults such as tobacco powder borers in tobacco leaves can be killed, so that the treated tobacco leaves can be safely stored; 3) The green miscellaneous gas of the removed raw materials is changed in chemical components in the tobacco leaves in a high-temperature high-humidity environment, the green miscellaneous taste of the tobacco leaves is obviously reduced, the taste of the tobacco leaves can be obviously improved, and the tobacco material alcoholization effect is facilitated.
All three purposes are achieved by means of achieving a higher vacuum through the equipment vessel and adding moisture regaining steam to the vessel. The vacuum damping machine is the first process production equipment of a cigarette factory and a tobacco redrying factory, is also the necessary equipment of a processing plant of certain materials (such as purple vegetables), but has high operation energy consumption, which is one of the defects of the equipment, and has two main energy consumption sources:
firstly, evacuating energy consumption: because the tobacco leaf vacuum damping machine is added with saturated steam after vacuumizing, so that the tobacco leaves absorb the condensed moisture and are heated and humidified, the vacuum damping machine can generate a large amount of steam condensation in the damping process, the condensed water flows at the bottom of the box body in the damping process, the temperature of the condensed water is about 60-70 ℃, most of the material inlet and outlet time period after the damping process is finished can flow out of the box body, but the problems of uneven bottom of the box body and shorter self-flowing time are solved, and part of the condensed water cannot be discharged at the bottom of the box body and is kept at a certain temperature; after each working period, a large amount of steam condensate exists at the bottom of the damping machine, the vacuum degree in the container is required to be raised to about 750-1500 Pa from atmospheric pressure before the damping process is carried out, when the vacuum system evacuates the container, the boiling point of the condensate in the container is reduced along with the improvement of the vacuum degree, and a part of water is correspondingly evaporated to reduce the temperature of the condensate in the container, so that the condensate is balanced with the vacuum degree, and finally the water temperature in the container is reduced to a temperature value balanced with the vacuum degree, namely 6-10 ℃. When the box is evacuated, the temperature of the box body (stainless steel container) of the moisture regaining machine is also 60-70 ℃, and the box body can also transmit a large amount of heat energy to the condensed water, so that the evaporation capacity of the condensed water is increased, and the box body is cooled along with the evaporation of the water; if more water exists at the bottom of the box body, the evacuation load is larger, otherwise, the less water exists, the smaller the evacuation load is, the temperature drop of the box body is also small, and the energy consumption of evacuation is also small.
Second, the energy consumption of moistures: the humidifying process is started after the evacuation is finished, the whole space of the container is filled with steam, the box body cooled by the evaporation of water during the evacuation is heated and warmed by the added steam again, the cost is that the steam is condensed into water, and the box body with lower temperature consumes more steam.
In summary, the condensed water at the bottom of the existing vacuum damping machine box becomes a non-negligible evacuation load (a large amount of condensed water is vaporized and evaporated), which affects both production efficiency and damping process index, mainly because the structural defect of the existing damping machine causes unnecessary energy consumption, the structural problem of energy consumption waste is solved, and the existing damping machine needs to be improved by matching with an improved structure.
