Optimization of the sieving and rebagging process of food powders
Customer: Food company - Powder gelling agent
Customer requirement: A leading company in the food industry needs to improve efficiency and accuracy in a key production process: sifting the powders coming from the bulk bag emptying system and subsequently rebagging/re-packing the resulting products, divided into fine and coarse powders. In detail, the specific requests concerned:
- Bulk bag emptying without work cycle interruptions or dust dispersion of the material.
- Metered product flow for the centrifugal sifter.
- Efficiency in conveying powders to big bag filling stations.
- Accuracy in monitoring the weight of filled big bags.
- Hermetic sealing during the filling process to prevent product waste and contain dust.
Gimat solution
To effectively address these challenges, we have designed and implemented an integrated system that includes several key components.
- Gimat bulk bag unloaders, equipped with a vibrating hopper and a safety hoop element. The former allows continuous and complete emptying of the contents, minimizing the risk of interruptions. The second ensures the operator's safety by protecting them from the risk of crushing if the big bag loops break.
- Gimat rotary valve (shown model RV 200, capacity 3840 L/h): our patented rotary valve here ensures a measured and constant flow of product towards the centrifugal sifter.
- Centrifugal sifter: for fast and precise separation of particles, the rotary sifter (selected directly by the customer) has a compact design and is easy to clean, thanks to the extraction of the impeller.
- Flexible screw conveyors for a fast powder transfer (shown model MAR 80, capacity 1800 L/h): GIMAT flexible augers allow a gentle and continuous conveying, preserving the quality of the product without demixing. The internal spiral is easily removable for cleaning.
- Big bag filling stations with weighing systems: to ensure filling precision, each station is equipped with an advanced weighing system that monitors the weight of the big bags in real time, as requested by the customer.
- Inflatable sleeve for airtight seal: during filling, an inflatable sleeve ensures the hermetic closure of the big bag filling spout, preventing contamination and product losses.
