With the continuous deepening of China's reform and opening up and the accelerating process of global integration, retail supermarkets for quantitative packaged goods have sprung up all over the country. The General Administration of Quality Supervision, Inspection and Quarantine issued the No. 75 Order on Measures for the Supervision and Administration of Quantitative Packaging Commodities. In order to better implement the state's requirements for the supervision and management of commodity quantity, all retail commodity manufacturers, especially the food production industry, have arranged food measuring instruments and packaging measurement tests to ensure that packaged foods can meet the requirements of the above regulations. In addition, the smart combination scale is especially favored by the food production industry.
At present, the measurement work of some domestic food production enterprises mainly has the following problems:
The sense of enterprise measurement and legal system is weak, and the basic work of measurement management is poor. Some enterprises only pay attention to production or marketing, and do not pay attention to measurement management. Measurement personnel have not been trained in measurement and regulation knowledge, and no special personnel are responsible for measurement management. The accuracy of selected measurement instruments cannot meet the negative deviation requirements of quantitative packaging commodities. Conditions cannot meet the specified requirements, such as humidity, tilt, etc., the detection equipment is backward, and the means are not complete;
Quantitative packaging production equipment is backward. Although some joint ventures and state-owned enterprises have introduced better imported equipment and adopted modern automatic packaging, the accuracy of quantitative packaging products has been guaranteed from the hardware. However, nearly half of the domestic units are still in the level of manual packaging. The accuracy of packaging measurement is unstable, and human factors are large. Some of the enterprises have old packaging equipment, backward technology and poor measurement repeatability.
There is no effective control over the net content of quantitatively packaged goods. The first is that there is no clear regulation on the tare weight of the package. Second, some food production industry units are not in place. Some companies do not put the measurement problem of quantitatively packaged goods in their eyes. It does not matter whether the weight is more or less, and there is no reasonable provision for positive deviation. A food product produced by a food company is 10 grams per pack, with an estimated value of 2 to 3 cents. If so, the annual cost will increase by more than 20-30 million yuan.
As a manufacturer of quantitative packaging products, it is increasingly felt that there are higher requirements in terms of packaging accuracy, packaging speed, and packaging range. Traditional quantitative automatic packaging scales have been difficult to meet these requirements, and smart combination scales are precisely Developed under this request.
How to properly choose the right measuring instrument. According to the shape characteristics of the products produced by the company and the relevant national regulations, we select the quantitative packaging production equipment with appropriate accuracy requirements and stable measurement performance, and the measuring instruments used to check the net content of the quantitative packaging products. At present, there are two types of food measuring instruments used by food production enterprises at home and abroad: one is a multi-head intelligent combination scale (hereinafter referred to as a multi-head scale); the other is an intelligent linear scale. Although the linear scale can be weighed differently by multiple weighing heads, each weighing bucket is discharged to the packaging machine separately, but such scales have no combined function, and the measurement accuracy is not too high, generally applicable to: sugar, salt , MSG, milk powder, sesame and other daily foods, condiments, small granular, powdery materials quantitative weighing. And smart combination scale is composed of a number of weighing units with independent feeding and discharging structure, general intelligent combination The scale consists of 8 to 32 weighing units. The computer uses the arrangement and combination principle to automatically calculate the load of each weighing unit automatically, and obtains the combination of the best and closest quantitative values ​​for packaging. For example, a 10-head computer combination weigher produced by Zhongshan Tianye Packaging Machinery Co., Ltd. weighs each weighing unit during weighing, and reads the weight data of each weighing weight into the computer, and optimizes it by computer. Combination, according to the combination of mathematical principles and computer technology, a total of 1023 combinations can be achieved by ten weighing units, and the computer selects the combination closest to the target weight value from the 1023 combinations. In this way, the above-mentioned manual repeated matching and it is difficult to achieve quantitative values ​​can be solved.
Technical characteristics of computer combination scale:
1. Amplitude automatic adjustment function to optimize production pass rate (manual adjustment during operation);
2. The amplitude can be modified independently, and the operation is more convenient. 3. The weight in each hopper is displayed in real time during operation;
4. Discharge function in sequence to avoid material blockage, adapt to large particle materials 5. Multi-language control system 6.10-inch true color touch screen, friendly interface (can be connected to mouse, U disk, SD card);
7. IP65 grade waterproof and dustproof design, more suitable for wet and dusty work;
Another important feature of computer combination scales is that there are corresponding application technologies according to different materials, such as waterproof type, fragile type, easy stick type, mixed weighing, number weighing, etc., which can be applied to various aspects. need. Since the launch of the intelligent combination scale produced by Zhongshan Tianye Packing Machinery Co., Ltd., it has been widely used in packaging snack foods, candy, baking foods, puffing, with its fast weighing rate, high pass rate and good automation. Quantitative packaging for industries such as foods and frozen foods. It is favored and respected by the vertical (to bag) packaging machine industry, trade industry and food production industry at home and abroad.
