Combination scale: the gospel of granular food weighing and packaging

  • 2021-08-24

Combination scales are widely used in the quantitative packaging of granular food, potato chips, candy, puffed food, biscuits, frozen vegetable food and other industries due to its high-speed, high-precision weighing, and high degree of automation. The combination weigher solves the problem of large measurement errors caused by the small weight of a single piece, and reflects the revolution and superiority of the combination weigher in the field of packaging and weighing.

Granular food is a packaged food processed by frying and roasting (including steaming and roasting) with noodles, fruit and vegetable seeds, nuts, small nuts, etc. as the main raw materials, with or without auxiliary materials. As deep-fried. In the past, more than half of the production enterprises still stayed at the level of manual packaging. The packaging measurement accuracy was unstable and there were many human factors. Some enterprises had outdated packaging equipment, backward technology, and poor measurement repeatability. Take a food company as an example. This is a company specializing in the production of casual snacks. It has always used manual packaging before. The packaging speed can only reach 20 bags/minute. The average error value of single bag weighing is larger than 5g, that is, each bag (50g) Pack at least 5g or more due to inaccurate weighing. Based on the annual output of 5,000 tons, the company alone loses nearly 500 tons of products each year. However, the combination weigher has greatly improved the packaging accuracy and speed compared with traditional measurement methods.

Of course, other packaged foods include biscuits, salads or other bar-shaped foods. We can still use a combination scale or a special biscuit weighing machine to solve the problem.

At present, the weighing error of the combination weigher is 0.1-1.0g, the weighing range is 0-2500g, and the weighing speed can reach 180 times per minute. After the company adopts a combination weigher, the average error is 0.2-0.5g, that is, the weight loss of each bag of roasted food (50g) is reduced by more than 3 grams compared with manual weighing. Through the production and use of the combination weigher, the entire investment was recovered in less than half a year. At present, the company's similar production lines all use the combination weigher.

Another important advantage of the combination weigher is that it has corresponding application technology according to different materials, such as fragile type, waterproof type, viscous type, mixed weighing, etc., which can meet the needs of various aspects.
