Abstract

The utility model discloses an adopt device that adsorbs technology production food level potassium chloride contains following unit: it connects in order to dissolve unit, filter unit, multistage by macroporous resin adsorption purification unit, active carbon adsorption unit, concentrated crystallization unit, solid -liquid separation unit and dry unit. The utility model discloses a by macroporous resin adsorption purification is united active carbon adsorption and is got rid of octadecylamine, dodecyl morpholine and 2# oil in the industry potassium chloride to reach and purify industry potassium chloride, the purpose of producing food level potassium chloride.

Description

Absorbing process is adopted to produce the device of food-grade potassium chloride

Technical field

The utility model relates to a kind of device adopting absorbing process to produce food-grade potassium chloride.

Background technology

Food-grade potassium chloride is edible potassium chloride again, is colourless elongated rhombus or cubic system or white crystalline powder, and odorless, taste be salty, soluble in water, be dissolved in glycerine, be slightly soluble in ethanol.It can be used as savory agent and nutritional supplement with Some substitute salt, prevents people's Excess free enthalpy salt.In addition, Repone K is the same with salt be can be used in the food such as agricultural-food, fishery products, livestock product, fermentation, seasoning, can, ready-to-eat, can be added in proportion in various food, indispensable effect is played to food tissue state, color, smell and taste and food raw material cost control.

Along with China's sustain economic increases rapidly, for food-grade potassium chloride product provides the huge market space.Present stage food-grade potassium chloride production equipment for purify industrial potassium chloride.Stearylamine, dodecyl morpholine and 2# wet goods flotation agent is contained in the technical grade Repone K prepared by flotation crystallization apparatus, in existing device, the method removing flotation agent increases coagulant aids, then filter, filtrate is separated after crystallization, drying obtains not containing the Repone K of flotation agent, though but the Repone K obtained is not containing flotation agent, adds coagulant aids, cannot meet the requirement of food-grade potassium chloride.

Utility model content

The purpose of this utility model there are provided a kind of device adopting absorbing process to produce food-grade potassium chloride, effectively can remove stearylamine, dodecyl morpholine, 2# wet goods flotation agent organism, produces food-grade potassium chloride.

The technical solution of the utility model is: a kind of device adopting absorbing process to produce food-grade potassium chloride, is characterized in that comprising with lower unit: dissolve unit, filtering unit, multistage macroporous resin adsorption purification unit, activated carbon adsorption unit, condensing crystal unit, solid-liquid separation unit and drying unit and be linked in sequence.

This device comprises dissolving unit, filtering unit, multistage macroporous resin adsorption purification unit, activated carbon adsorption unit, condensing crystal unit, solid-liquid separation unit and drying unit, by macroporous resin adsorption purifying, stearylamine, dodecyl morpholine and the 2# oil in industrial potassium chloride is removed in associating charcoal absorption, thus reach purified industrial Repone K, produce the object of food-grade potassium chloride.

The device difference that the utility model is compared increases coagulant aids is, removes stearylamine, dodecyl morpholine and the 2# oil in industrial potassium chloride mainly through macroporous resin purification associating activated carbon filtration.In whole device, macroporous resin and gac are by physical adsorption adsorb organic compound and impurity selectively from solution, thus reach the object of separating-purifying.

Accompanying drawing explanation

Fig. 1 is device schematic diagram of the present utility model.

Embodiment

As shown in Figure 1, the utility model comprises dissolving unit, filtering unit, multistage macroporous resin adsorption purification unit, activated carbon adsorption unit, condensing crystal unit, solid-liquid separation unit and drying unit, and concrete point following steps are implemented:

A) unit is dissolved: at room temperature, technical grade solid potassium chloride is dissolved as Klorvess Liquid;

B) filtering unit: one or several mixture adding food grade potassium hydroxide or salt of wormwood or potassium sulfate in Klorvess Liquid, allow other impurity such as a small amount of calcium ion, magnesium ion or barium ion in itself and industrial potassium chloride react, after reaction, obtain the throw outs such as calcium carbonate, magnesium sulfate or barium sulfate; To filter through strainer containing sedimentary Repone K crude product solution, and filter throw out, obtain Repone K primary solution I;

C) multistage macroporous resin adsorption purification unit: by step b) the Repone K primary solution that obtains is diluted to 5% ~ 20%, and Repone K primary solution I upper prop of 5% ~ 20% is adsorbed, obtains Repone K primary solution II.Stearylamine in macroporous resin adsorption process in primary attachment Repone K primary solution I, the Repone K primary solution II of the stearylamine that is removed;

D) activated carbon adsorption unit: by step c) in the Repone K primary solution II (effluent liquid flowed out by macroporous resin) that obtains pass through charcoal absorption, remove the dodecyl morpholine in Repone K primary solution II and 2# oil, obtain the Klorvess Liquid refined;

E) condensing crystal unit: by steps d) in the Repone K refined soln that obtains carry out acid adjustment neutralizing treatment, food grade citric acid is added or lactic acid makes Repone K refined soln be adjusted to neutral solution in acid adjustment process, after neutral Repone K refined soln is carried out concentration, carry out crystallization through crystallizer;

F) solid-liquid separation unit: by steps d) in Repone K after crystallization through solid-liquid separation, obtain the refined potassium chloride wet;

G) drying unit: by step e) in be separated the wet refined potassium chloride that obtains after super-dry, obtain purified diet grade potassium chloride.

Claims

1. adopt absorbing process to produce a device for food-grade potassium chloride, it is characterized in that comprising with lower unit: dissolve unit, filtering unit, multistage macroporous resin adsorption purification unit, activated carbon adsorption unit, condensing crystal unit, solid-liquid separation unit and drying unit and be linked in sequence.
