Problems solved by technology

At present, in the paper-making reconstituted tobacco industry, the concentration equipment is usually based on the multi-effect vacuum concentration system used in the pharmaceutical and food industries. Due to the complexity of the tobacco components, the concentration process has problems such as low efficiency and easy condensation on the inner wall of the heating tank, such as the concentration temperature. If the temperature is too low, the concentration time will be too long, which will

Abstract

The invention discloses a tobacco extracting solution concentrating method which comprises the following steps: 1) adding an adsorption clarifying agent into a tobacco extracting solution according to the weight, reacting for 10-30 minutes, separating through a butterfly type separator, and collecting the tobacco extracting solution; 2) pre-heating the separated tobacco extracting solution to 40-60 DEG C; 3) pumping the pre-heated tobacco extracting solution into a vacuum concentrating heating tank of an ultrasonic transmitter arranged on the outer wall, and conducting vacuum concentration. According to the tobacco extracting solution concentrating method, the concentrating quality and the concentrating efficiency of the tobacco extracting solution are improved, and the growth of scale particles is inhibited and removed, so that the service life of equipment is prolonged, and the labor intensity is alleviated.

Description

Technical field [0001] The invention belongs to the technical field of tobacco manufacturing, and specifically relates to a method for concentrating a tobacco extract. Background technique [0002] Domestic paper-making reconstituted tobacco is usually produced by a two-step method. First, the effective ingredients of the tobacco are fully soaked in a solvent, and then the tobacco extract is concentrated and backfilled on the tobacco substrate. The key production processes include extraction, concentration, papermaking, and coating. Waiting for the process. Tobacco extract usually contains a certain amount of protein, pectin, cellulose, hemicellulose and other macromolecular substances. These components are generally present in the extract in the form of solid suspension. Only by separating these solid suspensions can they be guaranteed product quality.
