From raw materials to finished products: the production process of laundry pods

The production process of laundry pods is a complex and systematic process involving multiple links, from the preparation of raw materials to the packaging of the final product. The following is the detailed process of producing laundry pods and the equipment required for each step.

1、 Raw material preparation

Before producing laundry pods, various raw materials need to be prepared, including surfactants, additives, fragrances, dyes, and capsule materials.

Equipment requirements:

Raw material storage tank: used to store liquid and powdered raw materials.

Weighing equipment: used to accurately weigh various raw materials to ensure the accuracy of the formula.

2、 Mixed

Mix various raw materials according to the formula requirements to ensure uniform composition.

Equipment requirements:

Blender: For liquid laundry pods, a horizontal or vertical mixer is usually used. For powder laundry pods, use a trough mixer or V-type mixer.

Mixing device: During the mixing process, there must be a mixing device to ensure that the ingredients are fully blended.

3、 Granulation (for powder laundry pods)

In this step, the mixed powder needs to be granulated to form granules for subsequent operations.

Equipment requirements:

Granulator: wet or dry granulator can be selected, and spray dryer is usually used for wet granulation.

Drying equipment: if wet granulation is adopted, a fluidized bed dryer or a spray dryer is required to remove excess water.

4、 Capsule production (for capsule laundry pods)

If producing laundry pods in capsule form, it is necessary to fill the capsule shell with liquid or solid.

Equipment requirements:

Glue making equipment: used for manufacturing capsule shells, usually using gelatin or plant-based materials, the equipment needs to have heating and cooling functions.

Filling machine: Fill the mixed liquid or powder into the capsules, ensuring that the weight and material of each capsule are consistent.

5、 Forming and curing (for capsule laundry pods)

After capsule filling, a curing step is required to ensure its shape and stability.

Equipment requirements:

Cooling system: Cool the filled capsules to solidify the capsule shell.

Quality inspection equipment: Inspect the cured capsules to ensure that their appearance and function meet the standards.

6、 Filling (for liquid laundry pods)

For liquid laundry pods, the mixed liquid needs to be filled into pre made capsules or pod shells.

Equipment requirements:

Filling machine: It can be a quantitative filling machine to ensure consistent liquid volume for each pod, usually using an automated filling production line.

7、 Packaging

Whether in powder, liquid or capsule form, laundry pods need to be packaged for easy transportation and sales.

Equipment requirements:

Packaging machine: Depending on the product type, automatic heat sealing packaging machine, vertical packaging machine, or box packaging machine can be selected to ensure good product sealing.

Labeling machine: used to attach labels to packaging, including product information and usage instructions.

8、 Quality inspection

Quality control is crucial throughout the entire production process. Every step requires necessary quality inspection to ensure that the final product meets the standards.

Equipment requirements:

Quality testing instruments, such as pH meters, viscometers, solubility testers, etc., are used to test various performance indicators of products.

Visual inspection system: used to detect appearance defects and packaging integrity of products.

9、 Storage and Shipping

Finally, the finished product needs to be stored in a suitable environment and shipped according to the order requirements.

Equipment requirements:

Storage system: Design a reasonable storage area to ensure the safe storage of finished products and avoid moisture or contamination.

Transportation equipment: such as forklifts, used to move finished products between warehouses and transport vehicles.

The production process of laundry pods covers multiple stages from raw material preparation, mixing, granulation, capsule production, filling, packaging to quality inspection. Each stage has specific equipment requirements, providing a guarantee for efficient and stable production. Enterprises should allocate equipment reasonably based on production scale and product type to achieve optimal production efficiency and product quality.
