Through the reciprocating motion of the piston within the cylinder barrel, the sauce is sucked from the hopper into the cylinder barrel. Subsequently, the piston pushes the sauce out, which then flows through the filling head and into the packaging container. For instance, the DG - 50 broad - bean paste filling machine of Dingguan Machinery operates on this principle and can precisely fill high - viscosity sauces with large particles.
The flowmeter is utilized to accurately measure and control the flow rate of broad - bean paste. Based on the set filling volume, when the flowmeter detects that the corresponding amount of sauce has passed through, the control system shuts off the filling valve, thus completing the filling process.
It consists of components such as the hopper and conveying pipelines. The hopper is used to store broad - bean paste, and the conveying pipelines transport the broad - bean paste from the hopper to the filling head. Some filling machines' hoppers are equipped with a stirring device to prevent the broad - bean paste from sedimentation and stratification, ensuring the uniformity of the sauce.
Common methods include piston - type measurement and flowmeter measurement. These methods can accurately control the filling volume of broad - bean paste, ensuring the consistency of the filling volume per bottle and meeting the requirements of different packaging specifications.
This is the component that directly fills the broad - bean paste into the packaging container. Its design varies according to the characteristics of the broad - bean paste and the type of packaging container. For example, for broad - bean paste that is prone to foaming, the filling head can adopt sub - merging filling to prevent the generation of foam and the overflow of materials.
Generally composed of components like PLC and a touch - screen, it enables the automated control of the filling machine. Operators can set parameters such as filling volume, filling speed, and the number of filling heads through the touch - screen. The control system then controls each component to work in coordination according to the set instructions.
This type requires manual bottle - loading and bottle - unloading, while the filling machine performs the quantitative filling operation. Its structure is relatively simple, and the price is relatively low. It is suitable for small - and medium - scale production enterprises or start - up entrepreneurs. For example, some small sauce workshops can choose the semi - automatic sauce filling machine of Jinan Xunjie Machinery Manufacturing Co., Ltd. It offers relatively flexible manual operation, occupies a small area, and has a low cost of investment.
It can automate a series of processes from bottle transportation, positioning, filling to capping and labeling. It features high production efficiency and high filling accuracy, effectively reducing labor costs and the impact of human factors on filling quality. For example, the broad - bean paste filling machine of Wenzhou Zhonghuan Intelligent Machinery Co., Ltd. has a filling speed of 40 - 80 bottles per minute and is suitable for large - scale broad - bean paste production enterprises.
By employing advanced measurement systems and control technologies, the filling accuracy can be maintained at a high level, generally within ±1%, reducing sauce waste and cost losses.
It is applicable not only to the filling of broad - bean paste but also to various viscous sauces such as chili sauce, peanut butter, and sesame paste, demonstrating strong versatility.
It has functions such as automatic feeding, filling, counting, and alarming. Some models can even be linked with subsequent packaging equipment to form an automated production line, enhancing production efficiency and the stability of the production process.
Based on the production scale and output requirements of the enterprise, select a filling machine with an appropriate filling speed and number of filling heads. For example, small enterprises with low initial production volumes can choose a filling machine with a slow filling speed and single - or double - head options. Large enterprises, on the other hand, need to select a high - speed, multi - head fully - automatic filling machine to meet the demands of large - scale production.
For brand - conscious enterprises and those with high product - quality requirements, equipment with high filling accuracy should be chosen to ensure that the product's weight or volume meets the standards and improve product - quality consistency.
Components in contact with broad - bean paste, such as the hopper, cylinder body, piston, and filling head, should be made of stainless - steel materials that meet food - hygiene standards or other non - toxic and corrosion - resistant materials to ensure that the sauce is not contaminated.
