When the chocolate chip depositor machine is running at high speed, it is a key technical issue to ensure that the chocolate beans do not stick or block the pipe. To achieve this goal, equipment manufacturers usually use a variety of design and process means to optimize performance. The following are specific methods and principles:
Material selection and surface treatment
Use anti-stick materials: The pipe and contact surface are usually made of food-grade stainless steel or other materials with a low friction coefficient (such as Teflon coating) to reduce the adhesion between the chocolate beans and the surface.
Smooth surface treatment: Polish the inner wall of the pipe to ensure that its surface is smooth and burr-free, thereby reducing the possibility of chocolate beans getting stuck.
Temperature control
Heating system: Chocolate beans are easily softened or even melted due to temperature changes, so the depositor is usually equipped with a temperature control device to keep the temperature in the pipe stable and prevent the chocolate beans from sticking due to overheating.
Cooling system: For chocolate beans with a high melting point, a cooling function may be required to prevent them from softening due to excessively high ambient temperature.
Vibration and airflow assistance
Vibration device: Install a vibrator in the pipeline to help chocolate beans flow smoothly through slight vibration to prevent accumulation or jamming.
Airflow blowing: Use compressed air to transport chocolate beans from one component to another while avoiding adhesion. This method is particularly suitable for small or lightweight chocolate beans.
Design optimization
Reasonable pipe diameter design: The pipe diameter should be slightly larger than the maximum size of the chocolate beans to ensure sufficient space for the chocolate beans to move freely.
Tilt angle adjustment: The pipeline is designed with a certain tilt angle, using gravity to assist the chocolate beans to flow downward and reduce the risk of blockage.
Multi-channel diversion: For large-flow production, a multi-channel design can be used to disperse the chocolate beans into multiple paths and reduce the pressure of a single pipeline.
Chocolate bean pretreatment
Screening and grading: Before entering the delivery machine, the chocolate beans are screened to remove unqualified debris or oversized particles to ensure that all chocolate beans are of the same size.
Moisture-proof measures: Chocolate beans are easy to absorb moisture and cause adhesion, so they need to be kept dry during storage and transportation, and the humidity should be checked before delivery.
Automatic monitoring and cleaning
Sensor detection: Install sensors at key locations to monitor the flow of chocolate beans in the pipeline in real time. Once signs of blockage are found, the system will automatically alarm and start the cleaning procedure.
Automatic cleaning function: Some high-end dispensers are equipped with automatic cleaning systems, which use clean water or compressed air to thoroughly clean the pipeline after each production to prevent residue accumulation.
Operation parameter adjustment
Speed control: According to the size, shape and fluidity of the chocolate beans, adjust the operating speed of the dispenser to avoid blockage caused by too fast.
Pressure regulation: For dispensers that rely on air pressure to drive, accurately control the air pressure to ensure smooth transportation without damaging the chocolate beans.
Regular maintenance and care
Regular inspection: Operators need to regularly check whether the pipeline is worn or deformed, and replace damaged parts in time.
Lubrication and cleaning: Although chocolate bean dispensers usually do not require traditional lubrication, it is still very important to regularly remove tiny residues in the pipeline.
Through the above methods, the chocolate bean dispenser can effectively avoid adhesion and blockage problems when running at high speed, ensuring the continuity and stability of the production process. These technologies not only improve the efficiency of equipment, but also reduce downtime and maintenance costs, and are an important guarantee for the modern food processing industry.
