The Swivel Valve cooler operates by sucking air through a product bed which is variable in height. New product is continuously fed
in through the inlet valve while the Swivel Valve discharger ensures smootrh discharging of cooled product into the hopper. Bridging of the product bed is avoided by gently lifting the product bed before discharging.
The discharge system is triggered by level or temperature sensor and driven by hydraulic cylinder and
power pack. Open and closed positions of the discharger can be adjusted either manually or remotely by
controller or PLC.
The Swivel Valve discharger can handle any type of granular product. It is also the cleanest discharge system
available, leaving no product in the cooler after emptying.
Sizes and capacities
Multiple sizes are available, each with different cooling surface area’s. In
combination with your process details, the cooling surface determines the
air volume that is required for proper cooling. Bin walls are available off
the shelf in several sizes, or alternatively they can be custom made to your
specifications.
Material specification
Every cooler consists of stainless steel inlet valve, hood, product distributor
and bin walls. The discharger and hopper can be optionally delivered
in stainless steel as well.
Clean out
Clean out is simple and effective. By driving the hydraulic cylinder to its
fully open position, the discharger will drop all product remains into the
hopper. Hatches or wide doors with safety switch provide access to the
cooler and hopper for inspection and cleaning.
Cooler fire safety
A fire valve in the hood cuts off the supply of fresh air in case temperature in the cooler reaches a pre-set limit (optional).
Operator safety
Sensors and control systems ensure that no access to the inside of the equipment is possible without first shutting down all moving parts (standard).
Bevelled corners
Bevelled corners in the hopper ensure that no product or fines build up in this vulnerable place (standard).
Remote Discharge control
Remote control of discharge settings on a Swivel Valve cooler is possible with the angle encoders which provide an mA signal to the controller, enabling the operator or plant control system to select different discharge configurations for different products (optional).
Cooler insulation
Insulation of the hood and bin walls leads to a significant reduction in the risk of internal condensation (optional).
Air flow control
With Automatic
Air Flow Control Valves air volume can be accurately controlled. There is automatic stabilisation of air volume, irrespective of the bed depth and the required air volume can be recipe dependent. No more blow holes during start up or emptying, no more excessive amounts of fines flying into the cyclone (optional).
Absorption of fats
When fats are added just upstream of the cooler, the Geelen Clam Shell Valve will ensure a thorough absorption into the product before cooling starts. This reduces pollution of the air system and product (optional).
Efficient change over
An Intermediate Gate installed above the main cooler deck will reduce the downtime in between any two product runs, without any compromise to efficiency or product quality (optional).
