Abstract
The invention relates to film-wiping type calcium lactate evaporating process. A concentrated calcium lactate solution is evaporated by adopting a film-wiping type evaporating device. The film-wiping type evaporating device comprises a transmission mechanism, an evaporating chamber, a wiping plate and a residual-heat utilization device. The technical scheme of the process is that: after the calcium lactate solution enters the evaporating chamber, a calcium lactate film is formed on the outer wall of the evaporating chamber by using a distributor, the transmission mechanism drives the wiping plate to rotate, the wiping plates enables the calcium lactate solution film to completely exchange heat with heating steam outside the evaporating chamber so that water in the calcium lactate solution is evaporated so as to improve the concentration, secondary steam generated by the evaporating chamber enters to the residual-heat utilization device, and the concentrated calcium lactate solution is discharged from a material outlet. The invention has the advantages of complete utilization of heat in the process of evaporating the calcium lactate, energy and investment saving and production efficiency improvement in the production process, capability of continuous production, small occupation area, simple process and convenience for operation, and is suitable for massive production.
Description
Technical field
The invention belongs to the calcium lactate production technical field, be specifically related to a kind of scraped film type calcium lactate evaporation technology.
Background technology
Calcium lactate is a kind of calcium-nutrition intensifying agent, and molecular formula is (C
6H
10O
6Ca), finished product calcium lactate outward appearance is white powder or particle, and slightly bitter taste is soluble in water, is used for fields such as food, beverage, medicine, feed, mainly as supplement calcium.The production main method of existing calcium lactate mostly is crystallisation and synthetic method greatly, when adopting these two kinds of methods to produce calcium lactate, because the calcium lactate solution initial concentration is lower, the calcium lactate of low concentration must be carried out the subsequent processing production of being allowed for access after the evaporation and concentration, the calcium lactate solution that is about to 10-20% is concentrated into 30～60% concentration, carry out crystallization, oven dry, pulverizing then, make the calcium lactate finished product.
Adopt crystallisation and synthetic method to produce calcium lactate, required energy consumption accounts for 40% of calcium lactate energy consumption when concentrating, method for concentration mainly contains modes such as economic benefits and social benefits or multiple-effect evaporation, falling film evaporation, built-in circulating and evaporating, and these methods are produced calcium lactate ubiquity energy and utilized problems such as insufficient, that production efficiency is low.Patent 200810039028.0 has been introduced a kind of " three-effect counter flow evaporation plant ", though there is energy consumption slightly to reduce, owing to adopted three groups of counter flow evaporation plants, its equipment investment is big, big, not high, the complicated operation of production efficiency take up room.Therefore, existing calcium lactate production need seek a kind of can be energy-conservation, the vaporising device of can reduce investment outlay again, enhancing productivity.
Summary of the invention
Purpose of the present invention is exactly when producing at current calcium lactate, the shortcoming and defect part that evaporation mode exists, and then a kind of scraped film type calcium lactate evaporation technology is provided.
A kind of scraped film type calcium lactate evaporation technology of the present invention, its technical solution are to adopt the scraped film type vaporising device to come the evaporation and concentration calcium lactate solution, and device is made up of transmission mechanism, vaporization chamber, scraper plate, residual heat using device.After calcium lactate solution enters vaporization chamber, make calcium lactate on the vaporization chamber outer wall, form the calcium lactate liquid film by distributing device, transmission mechanism drives scraper plate and rotates, scraper plate makes calcium lactate liquid film and the abundant heat exchange of vaporization chamber external heated steam, moisture in the calcium lactate solution is evaporated, concentration improves, and the indirect steam that vaporization chamber produces enters residual heat using device, and the calcium lactate solution after concentrating is drawn out of from material outlet.
The described transmission mechanism of the technology of the present invention solution, adopt the adjustable speed frequency control motor to drive spindle operation, the electric machine speed regulation scope is 30-300r/min, transmission mechanism drives main shaft, stripper cell is housed on the main shaft, scraper plate is housed in the stripper cell, and scraper plate has the 1-3cm gap in stripper cell, and scraper plate is movable under action of centrifugal force.
The described scraper plate of the technology of the present invention solution is fitted with the vaporization chamber outer wall, and the applying gap is 2-5mm, and vane material is a telfon plastic.
The outlet of the described residual heat using device of the technology of the present invention solution and vaporization chamber indirect steam is connected, and indirect steam and the air inversion by residual heat using device carry out heat exchange, add hot-air and enter the calcium lactate drying system.
Of the present invention producing effect is: adopt a kind of scraped film type calcium lactate evaporation technology; heat energy is fully utilized in the whole process of production; production process can be energy-conservation; reduce investment outlay again, enhance productivity; and can produce continuously; floor space is little, technology is simple, handled easily, is fit to large-scale production.
