Bag tipping stations for raw materials

In the foreground, to the left, is bag tipping station 1. This transfers whey powder and processed sugar to silos 1 to 4. In the mid-ground is bag tipping station 2, which transfers the milk powder, creamer and cacao to silos 5 to 8. In the far background, to the right, is bag tipping station 3, which transfers premix to weighing hopper 4.To the right of each station is a mechanical conveyor which transfers 25kg and 50kg bags of material from the ground floor below. In the floor opening beneath each station is the top of the vibratory sifter. The monitors next to the stations are HMIs. Each bag tipping station also has a chain hoist to handle one-tonne big bags. This, however, is not in the photo.

See pictures of the bag tipping station for minor ingredients.

More on how the bag tipping station area functions in the unloading stage.

Vibratory sifters and rotary valves

The machines to the left and middle foreground are the vibratory sifters for bag tipping stations 1 and 2. In the background, to the right, is the sifter for station 3. At the top of each sifter is a large, short, clear plastic attachment that connects it to the tipper above. Material is dropped from the stations into these sifters, which sieve them to remove any oversized particles. The sieved material is meted out by the rotary valves at the bottom of each machine, then pneumatically conveyed to the storage silos or weighing hopper 1.The pipework coming in from the right side and passing under the sifters 1 and 2 is three inch 316 stainless steel with short radius bends. Cool dry air is fed in from a nearby dehumidifying unit, booster fan and two pressure blowers. In the background is the same type of pipeline to sifter 3, but it is under vacuum generated from pumps at the weighing hopper structure.

Pressure blowers and booster fan

To the right, in yellow casings, are two powerful pressure blowers. The air from these blowers passes through the nearby dehumidifier unit and booster fan. In a green casing to the background left is a booster fan. The dehumidifying unit, to the right of the booster fan, is connected with a short intake.The booster fan is used to increase output of the cool dry air from the dehumidifier unit. The air transfers material to the silos from tipping stations 1 and 2, also from the buffer hopper to the receiving hoppers. Above the booster fan is a custom-engineered intake manifold connected to the pipework that distributes the processed cool dry air to the blowers, silos and buffer hopper.

More on how the blowers and booster fan integrate into the unloading stage.

Camlock station

The camlock station manages the flow of raw materials from bag tipping 1 and 2 through the conveying lines to silos 1 to 8. It also manages the premix line from bag tipping 3 to the weighing hopper 1. Material comes from the sifters below and moves up into the processing plant. Raw materials have a conveying rate of five to seven tonnes per hour.In the centre, two flexible hoses feeding into the pipework are for material being pressure conveyed (lean phase) to the silos. The flexible hose and pipeline to the far left are for vacuum conveying (lean phase) to a weighing hopper. The other six flexible hose lines carry cool dry air from the dehumidification unit to the top of the storage silos.

Stainless steel storage silos area

Three of the eight stainless steel storage silos. At the top are aspirators, while at the bottom are bin activators with rotary values. Material is pressure conveyed from tipping stations 1 and 2 to the top of the silos. Vacuum conveying is used to transport the raw material from the silos to the weighing hoppers.

More on how the storage silos work in the storage stage.

Bin activators and rotary valves

Each silo has, on the bottom, a stainless steel bin activator and a rotary valve. The rotary valves are connected to the bin activators with BFM flexible connectors and spigots. Material from the silo is dropped into the bin activator and fluidised. It is then meted out by the rotary valves and vacuum conveyed to weighing hoppers 2 to 4.

More on how the bin activators and rotary valves integrate into the storage stage.

Pipelines near weighing hoppers

The five pipes coming out of the top of the wall are from the silos. They run down along the floor and head off to weighing hoppers 2 to 4 using vacuum to convey raw materials. The pipeline closest in the foreground uses a Y-branch to increase system throughput. The non-abrasive nature of the materials allows for short bends to be used in the pipework.

More on how the dehumidifier and blowers use the pipelines to to provide cool dry air for the plant from the unloading stage.

Vacuum pumps

This set of vacuum pumps is near the weighing hopper structure area. These are used to lean phase vacuum convey raw materials from bag tipping station 3 to weighing hopper 1, and from the storage silos to weighing hoppers 2 to 4. The raw materials are powders such as whey, milk, creamer and cacao, as well as processed sugar and premix that comes in fine granules.

More on how the vacuum pumps integrate into the processing stage.

Buffer hopper

The buffer hopper receives the final product from the paddle mixer above. Using dense phase vacuum, it conveys it to the receiving hopper above the packing machines. The hopper is built from 304 stainless steel. The pipework taking the final product to the receiving hopper runs under the hopper to the left side and up the wall. There is a diverter gate in the pipework halfway up the wall. This remotely sends the final product to one of the two receiving hoppers. In the background to the right are the vacuum pumps 1 to 4 used to move materials from silos and tipping station 3 to the weighing hoppers.
