This is the advantage and precaution of a biscuit cooler.

Feb. 03, 2026

A biscuit cooler is a specialized piece of equipment used in the biscuit manufacturing industry. Its function is to rapidly cool freshly baked hot biscuits to room temperature or below, preventing them from deforming, softening, or spoiling. With the continuous development of the biscuit industry, biscuit coolers have become an indispensable and crucial component of biscuit production lines.

A biscuit cooler typically consists of a conveyor belt, a fan, and a refrigeration system. During operation, the conveyor belt transports hot biscuits from the oven to the cooling chamber, where the fan continuously circulates the air, rapidly lowering the temperature and achieving rapid cooling of the biscuits. The addition of a refrigeration system further enhances the cooling effect and speed.

Biscuit coolers offer several advantages:

1. Improved Biscuit Quality: Biscuit coolers quickly cool hot biscuits to room temperature, preventing them from softening or deforming due to prolonged storage, thus improving the quality and taste of the biscuits.

2. Increased Production Efficiency: Biscuit coolers can rapidly cool large quantities of hot biscuits in a short time, improving the production efficiency of the biscuit production line and reducing manufacturing costs.

3. Reduced Manual Intervention: Traditional biscuit cooling requires manual operation, which is not only time-consuming and labor-intensive but also prone to errors or improper operation that can lead to a decline in biscuit quality. Biscuit cooling machines, on the other hand, offer automated control, reducing manual intervention and improving production efficiency and quality stability.

When using a biscuit cooling machine, the following points should also be noted:

1. Cleanliness and Hygiene: Biscuit cooling machines accumulate a large amount of dust and bacteria over long-term operation, therefore, regular cleaning and disinfection are necessary to maintain hygiene.

2. Maintenance and Upkeep: The refrigeration system, conveyor belts, and other components of the biscuit cooling machine require regular inspection and maintenance to ensure the normal operation and lifespan of the equipment.

3. Safe Production: Biscuit cooling machines involve high temperatures and electrical components, requiring strict adherence to relevant safety operating procedures to prevent accidents.

In conclusion, biscuit cooling machines, as specialized equipment for the biscuit manufacturing industry, play an important role and offer significant advantages. During use, attention must be paid to cleanliness and hygiene, maintenance and upkeep, and safe production to ensure the normal operation of the equipment and the stability of biscuit quality.

Structure and Principles of Candy Molding Equipment

Jan. 25, 2026

1. 【Stamping Molding Machine】  

   - 【Main Components:】 Sugar delivery wheel, sugar strips, sugar scrap shovel, sugar scrap hopper, sugar unloading shovel, sugar unloading hopper, rotary head, cutting wheel.  

   - 【Description:】 Stamping molding is the primary method for forming hard candy. Initially, intermittent single-stroke machines were used, which could only process one candy piece at a time, resulting in low production efficiency. Today, continuous rotary stamping machines are more commonly used, capable of simultaneously stamping out multiple candy pieces, greatly improving production efficiency.  

   - 【Working Principle:】 The cooled and uniform sugar strips enter the molding machine, where the sugar delivery wheel, through friction, feeds the sugar strips into the rotary head. The strips are rolled into the outer edge of the molding slot and are pressed into shape by the cutting wheel, breaking the sugar strips into pieces. Simultaneously, the candy pushing rod, driven by a cam, moves forward to push the candy pieces into the molding holes. The pieces are then shoveled into the unloading hopper and fall onto a vibrating screen. Once the candy pieces cool down, they can be packaged.

2. 【Molding Injection Machine】  

   - 【Main Components:】 Conveyor belt, mold plate, sugar injection nozzle, sugar pouring pump, material storage tank, cooling device.  

   - 【Description:】 The molding injection machine can produce hard candies, soft candies, and gummies, making it highly versatile. The equipment required is generally similar across these applications. During the molding process, when the prepared sugar syrup is still in a liquid state, it is quantitatively injected into the continuously running mold plate, followed by rapid cooling and setting. Finally, the candies are separated from the mold plate and sent via a conveyor belt to the packaging machine.  

   - 【Working Principle:】 The sugar pouring pump pushes the syrup into the injection nozzle. It consists of two concentric cylinders: the outer cylinder is fixed and has a channel connecting it to the material storage tank, with a small hole at the bottom connected to the injection nozzle. The inner cylinder is a closing cylinder that has a connecting handle linked to a lever that swings left and right. Each side of the cylinder has small holes, and during swinging, the bottom hole closes while the side hole connects to the storage tank. When the side hole closes, the bottom hole connects to the injection nozzle. A piston is installed inside the closing cylinder, and when the piston moves up and down, it draws in air and pushes the syrup towards the injection nozzle. The distance the piston moves determines the amount of syrup discharged, which can be adjusted based on the size of the candy pieces. Each sugar pouring pump has a corresponding injection nozzle to ensure uniformity in the number of sugar molds.
