Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of phytate potassium production, and specifically relates to a phytate potassium production device. BACKGROUND

[0002] As an important raw material in the fields of food, medicine and industry, the potassium salt form (phytate potassium) of phytate salt has attracted much attention due to its high solubility and good bioavailability. The current mainstream preparation methods include direct extraction method, phytate neutralization with potassium salt and metathesis reaction method.

[0003] When phytate calcium is used as raw material for production, the traditional process needs to first decompose phytate calcium with strong acid to generate free phytate, and then react with potassium salt. However, there are problems such as large acid consumption, difficulty in separating by-products (such as calcium chloride), and low reaction efficiency.

[0004] In addition, the existing methods control the reaction conditions (such as pH and temperature) in a rough way, resulting in large fluctuations in product purity (85%-92%) and impurity residues affecting downstream applications. Some processes use multi-step purification, which can improve purity but increases energy consumption and waste liquid treatment cost, making it difficult to scale up. SUMMARY

[0005] The technical problem to be solved by the utility model is to provide a phytate potassium production device with low cost and high product purity in view of the deficiencies of the prior art.

[0006] To solve the above technical problems, the technical scheme of the utility model is as follows:

[0008] As an improved technical scheme, the outlet of the phytate calcium tank is connected with an air flow pulverizer through a pipeline, and the outlet of the air flow pulverizer is connected with the reaction kettle through a pipeline.

[0009] As an improved technical scheme, the solid phase outlet of the first centrifuge is connected with a calcium carbonate tank through a pipeline.

[0010] As an improved technical scheme, the inlet of the first centrifuge is connected with the deionized water tank through a pipeline.

[0011] As an improved technical solution, the outlet of the mother liquor recovery tank is connected to a decolorization tank via a pipeline, and the outlet of the decolorization tank is connected to the plate and frame filter press.

[0012] As an improved technical solution, the outlet of the frame filter press is connected to a precision filter, and the outlet of the precision filter is connected to the concentration tank.

[0013] As a preferred technical solution, the liquid phase outlet of the second centrifuge is connected to a crystallization mother liquor tank via a pipeline, and the outlet of the mother liquor tank is connected to the decolorization tank via a pipeline.

[0014] As a preferred technical solution, the solid phase outlet of the second centrifuge is connected to a washing tank, the inlet of the washing tank is connected to an ethanol tank via a pipeline, the outlet of the washing tank is connected to a third centrifuge via a pipeline, the solid phase outlet of the third centrifuge is connected to a dryer, and the outlet of the dryer is connected to the potassium phytate tank.

[0015] As a preferred technical solution, the liquid phase outlet of the third centrifuge is connected to a distillation tank, and the top gas phase outlet of the distillation tank is connected to an ethanol recovery tank.

[0016] Due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0017] This invention relates to a potassium phytate production apparatus, comprising a reaction vessel. The inlet of the reaction vessel is connected via pipelines to a calcium phytate tank, a deionized water tank, a potassium carbonate solution tank, and a dilute hydrochloric acid solution tank. The outlet of the reaction vessel is connected via pipelines to a first centrifuge. The liquid phase outlet of the first centrifuge is connected via pipelines to a mother liquor recovery tank. The outlet of the mother liquor recovery tank is connected via pipelines to a plate and frame filter press. The outlet of the plate and frame filter press is connected via pipelines to a concentration tank. The outlet of the concentration tank is connected via pipelines to a crystallization tank. The outlet of the crystallization tank is connected via pipelines to a second centrifuge. The solid phase outlet of the second centrifuge is connected to a potassium phytate tank. This reaction vessel is an ultrasonic reaction vessel. Inside the reaction vessel, calcium phytate undergoes a double decomposition reaction with added potassium carbonate. The pH is adjusted to 10-11 by adding dilute hydrochloric acid, generating calcium carbonate precipitate and a potassium phytate reaction solution. The potassium phytate reaction solution is centrifuged, filtered, concentrated, and crystallized. Finally, it is centrifuged again to obtain the potassium phytate product. This method yields high-quality potassium phytate with high purity and low cost, making it suitable for industrial production.

[0018] The outlet of the calcium phytate tank of this invention is connected to an air jet mill via a pipeline, and the outlet of the air jet mill is connected to the reaction vessel via a pipeline. Pre-treating the calcium phytate with the air jet mill allows it to be pulverized into finer particles, significantly increasing the contact area between the calcium phytate and other reaction raw materials, thereby effectively improving the reaction rate, making the reaction more complete, and ultimately improving the conversion rate of potassium phytate and the product quality.

[0019] The solid phase outlet of the first centrifuge is connected to a calcium carbonate tank via a pipeline. This allows for the centralized collection of solid calcium carbonate separated by the first centrifuge, facilitating further processing or recycling of the calcium carbonate and preventing environmental pollution from indiscriminate discharge. It also helps improve the comprehensive utilization rate of resources.

[0020] The inlet of the first centrifuge is connected to the deionized water tank via a pipeline. During the operation of the first centrifuge, deionized water can be introduced in a timely manner to wash the separated materials, effectively removing impurities remaining on the surface of the materials, further improving the purity of the product, and ensuring that the product quality is not affected in subsequent production processes.

[0021] The outlet of the mother liquor recovery tank is connected to a decolorization tank via a pipeline, and the outlet of the decolorization tank is connected to the plate and frame filter press. The mother liquor may contain some colored impurities. Decolorization treatment in the decolorization tank can effectively remove these impurities, resulting in a purer color in the subsequent product, improving the product's appearance quality, and enhancing its competitiveness in the market.

[0022] The outlet of the plate and frame filter press is connected to a precision filter, and the outlet of the precision filter is connected to the concentration tank. The precision filter can further filter out the tiny particulate impurities remaining in the mother liquor after processing by the plate and frame filter press, preventing these impurities from entering the concentration tank and affecting product quality during the concentration process. This ensures that the mother liquor in the concentration tank is purer, providing favorable conditions for subsequent crystallization operations.

[0023] The liquid phase outlet of the second centrifuge is connected to a crystallization mother liquor tank via a pipeline, and the outlet of the mother liquor tank is connected to the decolorization tank via a pipeline. Recovering the crystallization mother liquor and subjecting it to further decolorization for reuse reduces raw material waste and lowers production costs, while ensuring full utilization of materials throughout the production process, thus improving both economic and environmental benefits.

[0024] The solid phase outlet of the second centrifuge is connected to a washing tank. The inlet of the washing tank is connected to an ethanol tank via a pipeline. The outlet of the washing tank is connected to a third centrifuge via a pipeline. The solid phase outlet of the third centrifuge is connected to a dryer, and the outlet of the dryer is connected to the potassium phytate tank. Washing the solid-phase potassium phytate separated by the second centrifuge with ethanol effectively removes residual impurities and moisture. Further solid-liquid separation is then performed in the third centrifuge, followed by drying in the dryer. This yields a potassium phytate product with higher purity and lower water content, significantly improving product quality and meeting the stringent quality requirements of different customers.

[0025] The liquid phase outlet of the third centrifuge is connected to a distillation tank, and the top gas phase outlet of the distillation tank is connected to an ethanol recovery tank. By distilling the liquid phase separated by the third centrifuge through the distillation tank, the ethanol can be recovered, realizing the recycling of ethanol, reducing production costs, and reducing the pollution caused by ethanol emissions, which is environmentally friendly.

The pH is adjusted to 10-11 by adding dilute hydrochloric acid, producing calcium carbonate precipitate and a potassium phytate reaction solution. The potassium phytate reaction solution is then centrifuged, filtered, concentrated, and crystallized. Finally, it is centrifuged again to obtain the potassium phytate product. This method yields high-purity potassium phytate with low cost, making it suitable for industrial production.

[0031] The outlet of the calcium phytate tank 2 is connected to an air jet mill 12 via a pipeline, and the outlet of the air jet mill 12 is connected to the reaction vessel 1 via a pipeline.
