When purchasing a lobe - pump chili sauce filling machine, the following precautions should be noted:
1. **Clarify your own requirements**:
- **Production scale and output requirements**: For large - scale production, equipment with fast filling speed and high degree of automation should be selected. For example, a filling machine with a filling volume of several hundred bottles or even thousands of bottles per hour can be chosen; if the output requirement is not high, a small - sized semi - automatic or medium - low - speed filling machine can meet the demand.
- **Filling accuracy requirements**: For enterprises that focus on product quality and packaging specifications, filling accuracy is a key indicator. Select a filling machine that can meet the corresponding standards of filling accuracy according to the requirements of your own products. Generally speaking, a filling machine with an accuracy between ±0.5% and ±1% is more ideal.
- **Container specification and filling volume range**: Determine the size, shape of the chili sauce containers you need to fill and the volume range of each filling, and ensure that the filling machine can meet these requirements. For example, some filling machines can adjust the filling volume and adapt to multiple - specification containers, and this type of equipment has wider applicability.
2. **Pay attention to equipment performance**:
- **Lobe pump performance**:
- **Adaptability to material viscosity**: The viscosity of chili sauce varies. Ensure that the lobe pump has good adaptability to the viscosity of your chili sauce. If the chili sauce is too thick, a filling machine with higher power and a rotor design more suitable for high - viscosity materials should be selected to ensure smooth filling and avoid excessive wear on the pump.
- **Particle - handling ability**: If the chili sauce contains large chili particles or other solid particles, ensure that the rotor and filling port of the filling machine can pass these particles smoothly to avoid blockage. You can check the relevant parameters of the equipment or consult the manufacturer to understand its processing ability for particle - containing materials.
- **Self - priming ability**: A strong self - priming ability enables the filling machine to easily suck chili sauce without additional auxiliary equipment, improving the filling efficiency. If it is inconvenient to install auxiliary material - suction equipment at your production site, then a lobe - pump filling machine with strong self - priming ability is a better choice.
- **Equipment stability and reliability**:
- **Quality and durability**: Understand the overall quality of the filling machine, including the quality of the machine body material and parts. High - quality filling machines usually use sturdy and durable materials such as stainless steel, which can withstand long - term use and high - intensity work. You can check the production process, material certificates and other relevant information of the equipment.
- **Operation stability**: Try to understand the operation stability of the equipment before purchasing. You can view the customer cases and user reviews of the manufacturer, or go to the manufacturer to conduct a trial operation in person to observe whether there are faults, stalls and other problems during the long - term operation of the equipment.
3. **Control system aspects**:
- **Operation convenience**: A filling machine with simple operation and a user - friendly interface can reduce the training time and work difficulty of operators. Select a filling machine with an intuitive operation interface and easy parameter setting and adjustment for the convenience of operators.
- **Degree of automation**: Select a filling machine with an appropriate degree of automation according to your own needs. A filling machine with a high degree of automation can achieve functions such as automatic filling, automatic counting, and automatic shutdown, improving production efficiency and accuracy, but the price is relatively high; a semi - automatic filling machine requires manual assistance and is suitable for situations with low output or limited budget.
- **Fault diagnosis and alarm function**: The equipment should have the function of automatic fault diagnosis. When an abnormal situation occurs, it can send an alarm prompt in time, so that operators can quickly troubleshoot problems and reduce the impact of equipment downtime on production.
4. **Hygiene and safety standards**:
- **Material safety**: Since chili sauce is food, the parts of the filling machine in contact with the material must be made of food - grade materials, such as 304 stainless steel, which have good corrosion resistance and safety and will not pollute the chili sauce.
- **Sealing**: Good sealing can prevent the leakage of chili sauce and the entry of external impurities, ensuring the hygiene and quality of the product. Check the quality and installation of the seals of the filling machine to ensure that there will be no leakage problems during the operation of the equipment.
- **Safety protection**: The equipment should be equipped with necessary safety protection devices, such as emergency stop buttons, protective fences, etc., to ensure the safety of operators.
5. **After - sales service**:
- **After - sales response speed**: Select a manufacturer with good after - sales service, which can provide timely equipment repair, maintenance, and technical support. Understand the after - sales service network and response speed of the manufacturer. For example, when the equipment fails, whether the manufacturer can send someone to repair it on site in a short time.
- **Warranty period and scope**: Clarify the warranty period and scope of the equipment. Generally speaking, high - quality manufacturers will provide a long - term warranty period and comprehensive warranty services, including free replacement of parts, free repair, etc.
- **Technical training and support**: Whether the manufacturer can provide technical training for operators and continuous technical support during the use of the equipment is very important for the normal operation of the equipment and the skill improvement of operators.
6. **Manufacturer selection**:
- **Manufacturer's qualifications and reputation**: Try to select a filling machine manufacturer with a long history, complete qualifications, and good reputation. You can view relevant certificates such as the business license, production license, and quality certification of the manufacturer to understand the production experience and market reputation of the manufacturer.
- **Manufacturer's strength and scale**: Investigate the production strength and scale of the manufacturer, including production equipment, production process, and R & D capabilities. A powerful manufacturer usually can provide higher - quality products and more perfect after - sales service.
- **Price and cost - effectiveness**: On the premise of ensuring the quality and performance of the equipment, compare the prices of different manufacturers and select equipment with high cost - effectiveness. But don't just look at the price and ignore the quality and after - sales service of the equipment.
