Wheat Seed Treatment and Packing Equipment

Wheat Seed Treatment and Packing Equipment from Shijiazhuang Xinlu Technology Co., Ltd.

The processes of seed treatment and packing are critical value-adding steps that occur after wheat seed has been thoroughly cleaned and graded. Shijiazhuang Xinlu Technology Co., Ltd. offers integrated equipment solutions that cover these essential stages, preparing the seed for the market and ensuring its performance and traceability.

Seed Treatment Equipment:
Seed treatment involves the application of chemical or biological agents to the seed surface to protect it from soil-borne diseases, control pests during germination, and sometimes to provide essential micronutrients for early growth. The equipment is designed for accuracy, safety, and uniformity.

• Types of Treaters: There are two main types: batch treaters and continuous treaters. Batch treaters are suitable for operations that process specific lots with frequent product changes, allowing for precise recipe management. Continuous treaters are designed for high-volume processing, offering a constant flow of seeds through the treatment chamber.

• Precision Dosing: A fundamental component is the precision dosing system. This system meters the exact amount of liquid or slurry formulation (containing fungicides, insecticides, polymers, dyes, etc.) onto the seeds. Modern systems use advanced pumps and flow meters to ensure the application rate is consistent and accurate, which is crucial for both efficacy and cost control.

• Coating and Mixing Chamber: The heart of the treater is the mixing chamber, which can be a rotating drum, a vertical mixing cone, or a horizontal paddle mixer. Its purpose is to ensure that each individual seed is uniformly coated with the treatment formula. The design aims to achieve a smooth, even coating without causing damage to the seeds.

• Dust Management and Safety: Treatment applications can generate dust. Therefore, treatment equipment is equipped with effective dust extraction and filtration systems to protect operators and the environment. Safety features include enclosed systems to minimize exposure and rinsing mechanisms for cleaning between different treatment batches.

Seed Packing Equipment:
After treatment, seeds must be packed efficiently and securely for storage, distribution, and sale. The packing line is designed to handle the delicate, treated seeds while ensuring portion control and bag integrity.

• Weighing and Bagging: The process typically starts with a weighing scale. Depending on the required accuracy and speed, different scales are used, such as gross/net weighers or multi-head weighers for small packets. The weighed seed is then fed into a bagging machine. For wheat seed, common bagging machines include valve baggers for open-mouth sacks (e.g., 25-50 kg bags) and form-fill-seal (FFS) machines that create bags from a roll of plastic film, fill them, and seal them, which is common for smaller retail packages.

• Bag Sealing and Labeling: After filling, the bags need to be sealed. This can involve sewing for woven polypropylene bags, heat sealing for poly bags, or both. A critical step is the application of a label or the direct printing of information onto the bag. This includes essential data such as the seed variety, lot number, germination percentage, treatment information (including hazard symbols if applicable), packing date, and expiration date. Modern lines often include automated label applicators and inkjet printers.

• End-of-Line Automation: For large-scale operations, the packing line may extend to include automated palletizing, where filled bags are robotically stacked onto pallets, and stretch-wrapping to secure the load for shipping. This reduces manual labor and improves efficiency.

The integration between the treatment and packing stages is vital. Treated seeds often have a specified holding time before packing, and the equipment layout must facilitate a smooth, controlled transfer. Shijiazhuang Xinlu Technology Co., Ltd. focuses on designing lines that ensure treated seeds are packed in a way that maintains their quality and the efficacy of the applied treatments, providing a complete solution for seed companies to deliver finished, market-ready products.
