Self-service vending rice milling machine system and control method thereof

Abstract

The invention relates to the field of Internet of Things and the field of automatic control, in particular to a self-service vending rice milling machine system and a control method thereof. The ricemilling machine system comprises a main grain hopper, a rice huller, a rice miller, a grain husk separator, a spiral separator, a weighing rice hopper and a rice getting cabinet. During control operation, a vending, rice milling and filling process is completed through the steps that firstly, an order placement instruction is generated according to input data of a consumer, and a payment instruction is generated according to the order placement instruction; after payment is completed, a cloud payment switch sends out an adjustable pulse signal instruction to an automatic circuit, and the automatic circuit controls the rice miller to execute a rice milling action; after rice milling is completed, rice bran enters a rice bran storage cabinet through a cyclone separator, and rice enters the weighing rice hopper; and after the rice reaches weight selected by the customer, rice milling is stopped, the rice getting cabinet is opened, the rice is gotten, and the operation process is completed. According to the system, rice milling and vending are designed integrally, a user can eat fresh rice anytime, an unattended vending mode is realized, and performance is stable.

Description

Technical field [0001] The invention relates to the field of the Internet of Things and the field of automation control, in particular to a self-selling rice mill system and a control method thereof. Background technique [0002] Food safety has always been the focus of attention of the country and the people. Rice is an indispensable staple food for every meal. The health and safety status of rice involves the health of every family and everyone in the society. It is of great practical significance to ensure the health and safety of rice in the field of circulation and processing, and the process can be supervised, so that every consumer can participate in the supervision and inspection of processing. [0003] Nowadays, people go to supermarkets or food stores to buy rice processed by rice factories. Most of these rice have been stored in rice processing factories or store supermarkets for a long time, and they may deteriorate and do not meet hygiene requirements. Because the ri...

AI Technical Summary

Problems solved by technology

Since the rice bag is closed, people cannot determine whether the rice is added with various additives and whether the quality is good or bad in the process of processing.

In addition, in order to ensure a sufficient supply of rice to supermarkets and stores, rice processing factories can only pre-process a large amount of rice and perform polishing (removing the rice skin on the surface of the rice) at the same time, which increases the storage time of rice and causes rice to grow. Exposure to air for a long time will cause oxidation, mildew, moisture absorption, insects and nutrient loss, etc.

[0004] The existing automatic rice vending machines on the market only sell shelled rice. The disadvantages of this technology are: 1. The nutritional content of rice is lost

The pre-packaged rice is husked before use, because the husk is the natural protective layer of rice life and nutrition, after the rice is husked, the protein and vitamins will lose their activity within half a month, and the nutritional value will be greatly reduced

Second, the packaging cost is high

However, this type of rice milling machine basically uses a single-chip microcomputer or PLC to control the rice milling machine to achieve unattended operation, but it works in a humid climate and dusty environment, and the single-chip microcomputer is easy to misuse, which eventually leads to a high failure rate.

Moreover, this type of rice milling machine uses a single rice milling machine for rice milling work, and the rice produced is very broken or there are bran grains in the rice that comes out, which really annoys consumers
