Convenction Chamber Dryer SKKw with a detector of flammable substances – convection drying chamber, one door, mounted on feet, equipped with a DEX® gas detector. Automatic control based on algorithms agreed with the customer, control cabinet with a color touch display, automation equipped with barriers and EX separators, three-phase electric heater (3 x 1,8 kW / 400 V heaters) placed in the dryer’s base, radial fan for discharging air.

The air (normal 20⁰C) drawn from the hall by the intake hood with the air filter heated in the electric heater is sucked into the chamber through a truss placed in the chamber floor. Electric heaters separated from the chamber by a perforated metal plate. The processed air is discharged through the anemostat located in the ceiling of the chamber to the outside using a centrifugal fan located outside the hall or behind the dryer chamber.

The dryer works in a batch system.

Automation is based on Siemens or Schneider controllers.

The course of the drying process is monitored by means of measuring devices controlling the supply air temperature and the outlet air temperature.

TECHNICAL PARAMETERS AND EFFICIENCY

The efficiency depends on:

  • the type of material to dried material (fruits – apples, pears, plums, raspberries, strawberries, gooseberries, vegetables – carrots, beets, potatoes, peppers, cucumbers, garlic, herbs, mushrooms and nuts);
  • drying technology applied by the customer, including, among others, loading mass, drying temperature (variable during the full cycle), air flow rate, material disintegration level, expected quality of the dried product, etc.

In a large approximation, it is assumed that the installed 40 kW power can theoretically dissipate a maximum of 80 kg water/h.

In addition, when dealing with a delicate material, it should be known that exposure of this material to too high temperature and too much air flow can result in a very low-quality dried product. Additionally, it should be borne in mind that the drying process is not a linear process, which means that depending on the stage of the drying process, the amount of water discharged will change.

We offer drying machines equipped with an additional thermal power reserve, which is necessary at the beginning of the drying process in order to quickly warm up the material, and thus, a quick initiation of evaporation. The installed power must be adequate to the needs of the customer, who may want to dry eg. plums (which load is about 20 kg/m2), but also apple chips (which load is about 2 kg/m2).

The evaporation rate depends mainly on the degree of material disintegration, i.e. the ratio of evaporation surface to its volume, e.g. apple in slices of 7 mm thickness should get dried in 7-8 hours, while apple in 2 mm slices – in 2-3 hours.

 

SKKw Convection Drying Chamber is designed for drying food products, fruit, vegetables, herbs, fungi, biomass, as well as for drying the external surface of materials such as varnished clinker bricks, varnished facade tiles, varnished or resin body elements.

The dryer has 25 drying trays ​​0.5 m2 each.

Powered by electricity, natural gas or propane-butane gas.

As part of the additional equipment we offer trolleys that significantly improve the loading and unloading process of the load and allows for more efficient use of the machine.

The drying process takes place at a temperature of up to 80ºC and consists in taking moisture from the dried material through a stream of air at a suitable temperature. The heated air is distributed through diffusers located along the chamber. The processed air  is discharged throuhg fans.

The dryer works in a batch system. Depending on the type of dryer, the material to be dried is placed on trolleys or drawers. The walls of the dryer are made of silicate boards with mineral wool.

Automation is based on Siemens or Schneider controllers.

The course of the drying process is monitored by devices controlling air temperature (inside the chamber and at the exhaust). 

TECHNICAL PARAMETERS AND EFFICIENCY
  • Maximum heating power up to 600 kW
  • Lockable door (access restriction, sound alarm)
  • Alarm on reaching or exceeding the temperature
  • Left or right side door suspension
  • Culverts for wiring other devices
  • Short heating up time
  • We adapt each dryer to individual customer needs

Convection Chamber Trolley Dryer is designed for drying vegetables, fruits, granules, herbs, mushrooms. It is a one-door or two-door drying chamber equipped with one or two drying trolleys (for a dryer designed for more than two trolleys please see our Convection Tunnel Trolley Dryer).

The dryer is supplied from an electric, gas, oil or pellet heater.

The drying process is cinducted by bringing the heated air above/below each drying tray through diffusers placed in chamber walls. The direction of the air flow is changed cyclically. The dryer works in batch or continous mode.

Drying of the material takes place in a drying chamber on drying trolleys arranged on the track. The drying process consists in alternating supply of heated air under each drying tray through diffuser diffusers placed in the side walls of the drying chamber. The extracted air is discharged to the outside of the chamber through the outlet duct.

Dual-Chamber Convenction Dryer is designed for drying vegetables (carrots, potatoes, beets, vegetables), fruit (apples, bananas, plums, citrus, blackcurrant, fruit pulp), as well as for other drying materials, ex from the pharmaceutical industry.

Each dryer is made according to customer’s needs. This type of dryer is made in two alternative variants with different number of trays and their surface as well as the number of levels. The dryer consists of two autonomously operating chambers. In each chamber there is a place for drying trays with customized parameters (solid/perforated/openwork trays with high or low side + possibly equipped with a silicone mat (protection against sticking) or a mat of tefloned fiberglass).

The drying process can take place at temperatures of up to 80ºC and involves taking moisture from the dried material through a stream of heated air. The heated air is distributed using diffusers with diffusers.
