What machines are used for packaging flour？
Flour packaging equipment can be divided into three categories according to packaging specifications and automation degree. Each type of equipment corresponds to different production requirements. The following is a detailed description:
I. Automatic small bag packaging equipment (1-3kg)
This type of equipment is designed for the home or bakery. It is driven by a pneumatic system, which is more stable than traditional mechanical transmission. Taking Model 420 of a brand in Henan as an example, its core components include screw conveyor, PLC touch screen and film bag making device. During operation, the flour is raised to the storage bin through the screw rod, and the touch screen can set the packaging speed (5-30 bags/min), bag length (80-300mm) and other parameters, and the bag sealing is formed at one time. After the use of 720 equipment, a medium-sized bakery can complete 3 tons of flour packaging per day, and the qualification rate of sealing is 99.6%, which is especially suitable for customers who need to change the packaging design frequently.
- Semi-automatic medium bag packaging equipment (1-10kg)
This model is widely used in small processing plants, requiring manual bagging but equipped with photoelectric detection system. When the operator places the prefabricated bag at the discharge port, the device automatically senses and starts the screw metering and filling, and the accuracy is controlled within ±1% (that is, the error of 10kg packaging does not exceed 100g). The actual case shows that after using this equipment, a community flour factory can complete 1200 bags of packaging per hour, which is 8 times higher than pure manual efficiency and reduces flour dust by 90%. Key parameters include:
Power: 900W (equivalent to household microwave energy consumption)
Suitable bag type: self-standing bag, back seal bag
Upgrade option: can add vibration device to improve poor flow of flour filling
- Large capacity quantitative packaging machine (5-50kg)
For the wholesale market and food processing enterprises, the equipment supports woven bags and plastic bags dual mode. Its double-spiral feed system handles high-precision weighing (with an error equal to only two tablespoons of flour) and is equipped with a conveyor belt linkage sealing device. For example, when a large flour factory uses a 50kg model, it uses a heat sealing machine to deal with plastic bags and a sewing machine to deal with woven bags, achieving an average daily capacity of 80 tons. Core advantages include:
The microcomputer control system memorizes 10 groups of packaging parameters, and it only takes 3 seconds to switch specifications
The speed of the bottom conveyor belt is adjustable (0.5-2 m/s), suitable for different sealing equipment rhythm
Standard dust removal interface, can be connected to the workshop central dust removal system
Key indicators of equipment selection
Capacity matching:
Small workshop (daily production < 2 tons) : 1-10kg semi-automatic model
Medium-sized enterprises (2-20 tons per day) : multiple 1-3kg automatic equipment in parallel
Large factory (Nissan > 20 tons) : 5-50kg models + automated logistics line
Energy consumption comparison:
Automatic equipment consumes 2.2-5kW per hour (about 1.5-3.5 yuan/hour)
The pneumatic system needs to be equipped with an air compressor, which increases the air consumption by 0.4m³/min
Maintenance cost:
The screw conveyor rod needs to be replaced every 2000 hours (the cost is about 800 yuan)
The life of the thermal seal is about 150,000 seals (8 hours per day for 2 years).
Industry Application Examples
Baking raw material supplier: Using 3 520 automatic equipment, the daily production of 120,000 small packaging bags, packaging loss from 3% to 0.5%
Organic flour brand: customized stainless steel anti-corrosion models, through the FDA certification, successfully entered the North American high-end market
Rural cooperatives: use 5-50kg models with sewing charters to convert bulk flour into brand woven bags for packaging, and the product premium increases by 40%
Purchasing Advice
Carry common packaging bags (at least 5) field test machine to test the suitability of the bag clamp
It is preferred to choose manufacturers that support voltage customization (110V/220V/380V) to facilitate export demand
Inspect the size of the after-sales team of the manufacturer. High-quality suppliers should set up service stations in the main flour producing areas (such as Henan, Shandong and other places).
