Oil-free vacuum pump used in tobacco products _

in recent years, with the development of modern tobacco agriculture, the improvement of the barn and coal development of alternative energy sources has become more and more important in the production of tobacco. Farmers want to effectively improve the overall quality of tobacco and the proportion of upper leaves, but to achieve this goal, baking processing equipment and process conditions is the key. Oil-free vacuum water pump for large-scale, high efficiency, continuous production of high quality tobacco, tobacco farmers is an important guarantee of tobacco farmers really improve the economic benefit.

tobacco is a kind of thin film gel capillary porous materials. In tobacco production process, to remove part of free water and water adsorption of water, and water is relatively easy to remove. In view of the technical characteristics of tobacco production, should choose suitable for drying methods for large-scale continuous production, and easy to automatic control of tobacco in the process of production water and humidity.

how to test the tobacco drying and dehydration properties of?

tobacco drying and dehydration performance mainly by raw material processing, processing, transportation, packaging and storage in the process of the influence of moisture and temperature. Now the main dynamic vapor adsorption tests. Place the tobacco in the precise control of humidity - Temperature environment, in order to detect the tobacco on the adsorption and desorption of water, and the adsorption isotherm and kinetics of tobacco, diffusion and permeability, stability and the storage life and property. For your reference.

oil-free vacuum water pump application in tobacco products must grasp the following several points

1. Tobacco main yellowing temperature should be controlled in 35 - 38 ° C, dry bulb and wet bulb temperature difference between in 2 - shall be maintained 3 ° C, in order to make tobacco at 7 Eight yellow leaves are very soft.

2。 Complete the yellowing temperature control in the 40 - 35-42 ° C below, keep wet bulb temperature 37 ° C, the realization of basic yellowed leaves, withering all collapsed, main veins soft, guarantee the transformation of tobacco, more aroma formation matrix. Therefore, it is necessary in 41 - 42 ° C under the appropriate extension of the time, make the tobacco to yellow stripe blue stripes stripe, blade completely withered and collapse, the soft of arteries and veins.

3。 Should be according to the quality of tobacco leaves with the appropriate speed heating solid color phase, to master the proper humidity, ensure full yellow leaf, well fixed; For 46 - dry bulb temperature 48 ° C, wet bulb temperature of 37 - 38 ° C, the tobacco leaves, stem yellow, reach the yellow gluten little scroll.

4。 Will keep in 38 - wet bulb temperature 39 ° C, dry bulb temperature is about 54 ° C, and long pull big roll of tobacco leaves, in order to achieve this will promote the formation of more aromatic substances.

5。 Tobacco drying rib should be controlled in 65 - the highest temperature 68 ° C, wet bulb temperature should be controlled in 40 - 43 ° C, in order to increase the color of tobacco leaf and color, reduce the loss of tobacco aroma.

oil-free vacuum pump application in tobacco products not only save energy, avoid the pollution of the environment, and is suitable for the tobacco baking and baking process requirements, to improve the color of tobacco leaf and yield, thus improve the improve the quality of products, enhance product competitiveness, improve the market competitiveness of tobacco farmers and income. At the same time, oil-free vacuum pump not only can completely satisfy the requirements of tobacco market of baking equipment, also meet food drying, Chinese herbal medicine drying, rubber drying, drying technology, drying in areas such as electroplating parts requirements.
