The rapid economic development, the pace of life has prompted people to change the traditional way of life, as people are increasingly reluctant to spend more time in the kitchen, a new generation of consumer groups are growing, so that convenience food has always maintained good growth momentum in recent years. Huge business opportunities so that businesses are coming, convenience food will account for most of the Chinese food market. Potato chips occupy an important position in the casual food, and are loved by consumers of all ages. Humpback whale the customer is a famous food manufacturer, potato chips in the market share is very high, for the quality of attention is their work is the most important. The most important source of potato chips is potatoes, commonly known as potatoes, yams, ground eggs, yam eggs, which are formed into chips after storage treatment and processing. During the maturity season of potatoes, Humpback Whale's customer acquires potatoes in large quantities for storage through refrigerated vaults, and also faces the need for temperature, humidity, and carbon dioxide and oxygen monitoring to ensure the quality of raw potatoes and reduce cargo losses.

Challenge

Potatoes are suitable for storage at temperatures between 0-5 degrees and relative humidity between 60% and 90%, with an optimum temperature of 4 degrees and relative humidity of 85%-90%. Above such storage temperature, the tubers tend to sprout and crumple. When the temperature is between 0 and 1℃, the starch in the tuber starts to be transformed into sugar, and the taste becomes sweet and the seed potato becomes bad; when the tuber is lower than - 1℃, the tuber is frozen and then rots a lot. In this humidity range, the tubers do not lose much water and do not wilt, and at the same time, they do not rot due to excessive humidity. In addition, potatoes that have been stored for a period of time are affected by environmental factors and start to become soft and wilted and turn green and sprout. This is mainly due to the high temperature, high humidity, lack of ventilation and light in the storage environment. The green material on the skin of potatoes is partly chlorophyll produced by sunlight, which is not poisonous and can be eaten safely; partly lobotropin, which is formed by chemical reactions in potatoes under light conditions, is toxic. Lungwort is a toxic substance in potatoes, a toxic glycoside alkaloid, which is soluble in water and has corrosive and hemolytic properties. This substance is commonly found in potatoes and can cause acute poisoning when consumed in large quantities. The content of lobotropin in potatoes increases with temperature, in addition to photosynthesis, which also increases the content of lobotropin, necessitating close monitoring of temperature, humidity, light, carbon dioxide, oxygen, etc. when storing potatoes in cold storage to ensure food safety.

Solution

Humpback Whale Dart solution provides LoRa gateway with temperature and humidity probe and CO2 probe for accurate monitoring of temperature, humidity, light and CO2 content in the refrigerated vault, and cooperates with customers to set accurate threshold values to ensure that the temperature change interval is between plus and minus 1 degree, and focus on monitoring CO2 concentration in a reasonable range to avoid potato "poisoning "This prevents the occurrence of the phenomenon of potato poisoning and reduces or avoids the spoilage of potatoes. The appropriate concentration of CO2 concentration can also play a role in slowing down the respiration of fresh potatoes, which can effectively delay the initiation effect of respiratory leap. A robust over-threshold alarm mechanism helps customers to control various monitoring data within a reasonable range in real time. Once the threshold is exceeded, the alarm can be made through the platform, WeChat and SMS, prompting the warehouse to ensure the optimal storage conditions by adjusting the temperature, ventilation and other means, which is a complete inventory monitoring solution that provides a favorable aid to customers' raw material storage. This case involves whale dart products, LoRa gateway, temperature and humidity probes (including temperature, humidity and light sensitive), CO2 probes, etc.
