Water distribution device capable of intelligently controlling pH and application thereof

Abstract

The invention belongs to the technical field of food processing equipment, and relates to a water distribution device capable of intelligently controlling pH and application of the water distribution device in sterile rice production. The device comprises a water tank installed on a rack, and a cover body is arranged on the water tank; a stirring device and a pH sensor are arranged in the water tank; n branch pipelines are arranged on the cover body, and electromagnetic valves are arranged on the branch pipelines; one end of the branch pipeline penetrates through the cover body, and the other end is correspondingly connected with an acid liquor supply tank and a pure water supply tank through a metering pump; n is a positive integer greater than or equal to 2; a quantitative liquid taking device is communicated below the water tank; and the device further comprises a servo motor, wherein the servo motor, the stirring device, the metering pump, the electromagnetic valve, the pH sensor and the quantitative liquid taking device are all electrically connected with a PID control system. The pH value of the solution can be monitored, regulated and controlled on line in real time; an aqueous solution with proper pH is added in the rice water distribution process; and operation is easy and convenient, and meanwhile good quality and taste of rice are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of food processing equipment, and in particular relates to a water distribution device for intelligent pH control and its application in aseptic rice production. Background technique [0002] With the improvement of people's living standards and the continuous acceleration of the pace of work, the demand for instant food and the quality requirements are gradually increasing. As a convenient staple food that can be industrially produced, instant aseptic rice has received more and more attention. In order to ensure that the convenient aseptic rice maintains a high sensory quality in the subsequent transportation, storage and sales process, it is necessary to add an acidic aqueous solution with a suitable pH before cooking. This is because the addition of an acidic aqueous solution can improve the taste and color of cooked rice. and sticky. Therefore, in the production process of convenient aseptic rice, detec...

Problems solved by technology

[0003] There is no solution to the above problems in the existing technology, and it is still necessary to manually add the prepared acid water into the water tank. Manual work is not only time-consuming and labor-intensive, but also has human errors. Different liquid levels have different pH

If acidic aqueous solutions with different pH are added to instant food products, it will lead to serious differences in the taste and quality of instant food products.
