Food-grade packaging material migration quantity detection system

Abstract

The invention provides a food-grade packaging material migration quantity detection system. The system comprises a shell which is a box body structure, a soaking chamber, a soaking cylinder, a liquidinlet pipeline, an evaporation chamber, an electronic scale, an exhaust hood, a liquid outlet pipeline and a controller, wherein the soaking chamber is arranged on one side in the shell, and the soaking chamber includes a heating base arranged at the bottom end of the soaking chamber; one end of the soaking cylinder is arranged on the heating base; the evaporation chamber is arranged on the otherside in the shell, the evaporation chamber is divided into an evaporation layer and a heat insulation layer from top to bottom, and the evaporation layer includes a tray on which an evaporation dish is arranged; the electronic scale is arranged in the heat insulation layer; and the exhaust hood is arranged above the tray, a condenser is arranged at the tail of the exhaust hood, and a recovery tankis arranged under the condenser. A soaking process and an evaporation process are arranged in one device, the integrated process of food contact material soaking and simulant evaporation is achieved,and the defects that in the prior art, manual operation is tedious and low in efficiency are overcome.

Description

technical field [0001] The invention belongs to the field of food detection and relates to a detection method for total migration of food contact plastic products Background technique [0002] In the modern food production and distribution system, food contact materials play an extremely important role. They can be called the "coat" of food and are closely related to our daily life. Especially plastic products of food contact materials are loved by consumers because of their light weight, beautiful appearance, low cost, insulation, drop resistance, and corrosion resistance. If juice machines, coffee machines, plastic bowls, disposable tableware, etc. can be seen everywhere in our lives, it will bring us great convenience. However, while people pay attention to the quality of life, they often ignore the safety of materials in contact with food. In daily use, harmful substances may migrate from materials in contact with food to food, thereby affecting human health. This pro...

Problems solved by technology

At present, the amount of migration of food-grade packaging materials requires the operator to be on duty, which wastes manpower and material resources. At the same time, it also causes toxic solvents to be directly discharged into the atmosphere and cannot be recycled, causing pollution and waste, which does not meet the requirements of energy saving, emission reduction and environmental protection.
