Yesterday, when I went to the supermarket, I was catching up with ice cream and had a discount on activities. I grabbed a box of cones and rushed home after a busy day. After I went home, I was stunned by the low price of the sweet tube. The mini version that can be solved is not enough to eat. This is not to remind the author of the long-standing 'Pit Man Food Packaging' on the rivers and lakes. It can be filled in the place where it can be seen. Other places do not use foam, plastic, carton-filled packaging. Too common. In fact, it is also very simple to avoid such pitfalls. It is the quickest way to see the net content on food packaging.
In the "Food Safety Law of the People's Republic of China" issued by China, it is stipulated that the label of prepackaged foods needs to be marked with a net content. Therefore, no matter which kind of prepackaged food, the weight of the food is marked in the corner of the package. As long as they develop the habit of paying attention to food weight, they can avoid being deceived by some over-packaging. In the food production process, weighing packaging for food is mainly realized by measuring packaging machine.
There are many types of foodstuffs, so the measuring and packaging machine has also developed a wide range of products to suit the metering packaging of different ingredients. For example, screw metering powder packaging machine for powder metering packaging, weighing metering and packaging machine for granular materials, liquid for liquids Pump metering and packaging machines, etc. Currently, packaging equipment is equipped with different weighing combinations to achieve weighing packaging of all kinds of foods. It is combined with electronic scales for packaging of granular foods; combined with screw measuring machine for packaging of powdered foods. And with liquid filling machine packaging paste, liquid food, etc.
The weighing accuracy of the measuring and packaging equipment is related to the standardization of the produced food. Therefore, improving the precision of the measuring and packaging equipment is a major direction for the improvement and upgrading of such packaging machinery. In order to improve the packaging precision of liquid food, liquid packaging machinery has set a fast and slow speed. The method of automatic adjustment is converted into slow drip irrigation when the weight is set close to the package. In addition, the residual liquid is not dripped, which improves the measurement accuracy of the package. In the field of powder packaging machine, there may be a change in the specific gravity of the material. The phenomenon of weight change, some companies have found that weighing the weighing into a weighted feedback proportional tracking can successfully overcome this defect.
Metering packaging is a kind of food machinery equipment that directly contacts food. The equipment needs to be cleaned after use to ensure the safety of food production. Therefore, whether the equipment is easy to clean is an important indicator to measure the equipment. It is reported that there are equipments produced by enterprises, and boxes. It can be easily removed and removed without tools. Others can be set in a transparent style for easy stain cleaning.
As a major function of modern packaging, metering needs to be connected with other equipment to realize the full mechanization of production. It is reported that the current measuring and packaging equipment can be connected with various equipment such as sealing machine and filling machine. Automatic detection function, for some defective packaging (such as incomplete bag opening), automatic stop, avoiding waste of packaging materials, food and many other products, saving cost for food production.
Of course, for the characteristics of food materials packaging, the measurement packaging equipment needs to be partially improved, such as dusty flour and other products are easy to back spray when packaging, need to install a vacuum device at the material outlet; encounter ultra-fine powder In the case of food, it is easy to invade the spiral and cause equipment failure, pollution, etc., and the spiral attachment needs to be replaced. When some foods with too good fluidity are encountered, the final measurement may be inaccurate, and a centrifugal device may be added to ensure accuracy.
It can be seen that the metering and packaging is constantly upgrading in various aspects such as adapting foods in different states, improving accuracy, and being easy to clean. It is this rapid adaptation to the market that makes metering packaging an indispensable part of modern packaging equipment. Equipment type.
