Working Principle
The double screws are driven by a servo motor. The double screws perform synchronous rotational movements inside the pump body, enabling the seasoning to be continuously and stably pushed within the sealed cavity formed by the screws and the pump body, thus achieving precise conveying and filling from the material barrel to the packaging container. The rotation of the double screws can be precisely controlled by regulating parameters such as the rotation speed and the number of revolutions of the servo motor. Subsequently, the filling volume of the seasoning can be accurately adjusted to achieve high-precision filling measurement.
Main Types
According to the degree of automation: There are two types, semi-automatic and fully automatic. For the semi-automatic type, some processes require manual assistance, such as manually placing bottles and capping. The equipment has a relatively simple structure and lower cost, making it suitable for small and medium-sized production. The fully automatic type can automatically complete a series of processes such as material conveying, filling, capping, and labeling. It has a high degree of automation and high production efficiency, and is suitable for large-scale production.
According to the number of filling heads: There are single-head and multi-head filling machines. The single-head filling machine is suitable for production with small output and multiple varieties. The multi-head filling machine has multiple filling heads and can fill multiple packaging containers simultaneously, greatly improving production efficiency and is suitable for production scenarios with a large output.
Scope of Application
It can be widely applied to the filling of various liquid, paste, and granular seasonings. For example, liquid seasonings such as soy sauce, vinegar, cooking wine, etc.; paste and sauce seasonings such as ketchup, chili sauce, broad bean paste, peanut butter, etc.; it can also be used for seasonings with a certain particle size, such as beef sauce, mushroom sauce, etc. As long as the particle size is within the allowable range of the double-screw delivery pump, smooth filling can be achieved.
Advantages of the Equipment
High-precision filling: The driving mode of the servo motor in cooperation with the double screws can precisely control the filling volume, with high metering accuracy, and can control the weight or volume error of each bottle or bag of seasoning within a very small range.
Gentle material handling: The conveying method of the double screws exerts relatively small shearing force and extrusion force on the materials, which can well maintain the original quality, flavor, and particle integrity of the seasoning, especially suitable for seasonings containing particles or easily broken materials.
High adaptability: By adjusting the parameters of the double screws and the operating speed of the equipment, it can adapt to the filling of various seasonings with different viscosities and particle sizes, and the equipment has strong versatility.
Good stability: The overall structure of the equipment is robust, and key components such as the double screws and the servo motor have stable performance. During operation, there is little vibration and low noise. It can work continuously for a long time, with a low failure rate and relatively low maintenance costs.
Hygienic design: The components in contact with the seasoning are usually made of hygienic materials such as food-grade stainless steel. The surface is smooth, there are no sanitary dead corners, and it is easy to clean and disinfect, meeting the sanitary standards and requirements of the food industry.
Key Points for Purchase
Production capacity: Select according to the production scale and output requirements of the enterprise. Factors such as the filling speed of the filling machine, the number of filling heads, and the operating efficiency of the equipment need to be considered to ensure that the equipment can meet the enterprise's production plan.
Filling accuracy: For seasoning products with high accuracy requirements, select a filling machine that uses high-precision servo motors, double-screw metering systems, and advanced control systems to ensure the accuracy of the filling volume.
Characteristics of applicable materials: Select a suitable filling machine according to the characteristics of the seasoning to be filled, such as viscosity, particle size, fluidity, etc. If the material has a high viscosity or large particles, select a double-screw filling machine with a larger screw diameter and stronger conveying capacity.
Degree of automation: Consider factors such as the production needs, capital budget, and personnel allocation of the enterprise comprehensively. Although the initial investment of a fully automatic filling machine is relatively large, it can save labor costs, improve production efficiency, and product quality stability; a semi-automatic filling machine is more suitable for enterprises with limited funds or a small production scale.
Brand and after-sales service: Select a filling machine from a well-known brand, and its product quality, performance, and stability are usually more guaranteed. At the same time, good after-sales service is also very important, including equipment installation and commissioning, training, maintenance, and spare parts supply, etc., which can ensure that problems encountered during the use of the equipment are solved in a timely manner.
