The process flow of the self heating rice production line mainly includes the following key steps:
1、 Raw material preparation and mixing
Raw material preparation: Mix rice, water, and other necessary additives (such as seasonings, nutritional fortifiers, etc.) in a certain proportion according to the product formula. This step ensures the basic flavor and nutritional value of the product.
Mixing powder: Use a powder mixer to thoroughly mix the raw materials to ensure even distribution of each component, laying a good foundation for subsequent processes.
2、 Extrusion granulation
Conveyor: Use a feeder to transport the mixed raw materials to the feeding hopper of the extruder. The feeding machine usually adopts a spiral conveying method to ensure a fast and stable feeding process.
Squeezing granulation: Under the high-pressure environment of the extruder, the raw material is extruded into rice granules. The extruder is equipped with a dedicated control cabinet that can adjust process parameters and replace molds to produce rice grains of different shapes and tastes.
3、 Cooling and screening
Vibration cooling: The extruded rice grains contain a certain temperature and viscosity, which are spread out and cooled through a vibrating screen to avoid particle adhesion.
Screening: The rice grains cooled by vibration need to be further screened to remove particles that do not meet the requirements, ensuring the uniformity and quality of the product.
4、 Drying and sterilization
Drying: The screened rice grains are sent to a drying equipment for drying treatment to remove excess moisture, improve product stability and shelf life. Drying equipment usually uses multi-layer ovens, and the temperature and time are adjusted through a control cabinet to ensure the drying effect.
Microwave sterilization: During or after the drying process, microwave sterilization treatment is carried out to eliminate potential microorganisms and ensure the hygiene and safety of the product.
5、 Cooling and packaging
Cooling: The dried and sterilized rice grains need to be cooled to room temperature to ensure quality during the packaging process. Cooling conveyors are typically used for this step.
Packaging: Afterwards, send the cooled self heating rice granules into the packaging machine for packaging. The packaging machine can automatically complete bagging, sealing and other operations according to the set specifications and quantities, ensuring the sealing and aesthetics of the product.
6、 Quality inspection and warehousing
Quality inspection: The packaged self heating rice will undergo strict quality inspection, including testing of appearance, taste, nutritional content, etc., to ensure that the product meets relevant standards and customer requirements.
Warehousing: Products that have passed quality inspection will be sent to the warehouse for storage, waiting for shipment or sale.
In summary, the process flow of self heating rice production line is a complex and delicate process, involving multiple links and equipment. Each stage requires strict control of process parameters and quality standards to ensure the quality and safety of the final product.
