Overview
Dries lettuce, fruit and vegetables fully automatically, efficiently and hygienically: up to 2,800 kg (6,170 lb) of product per hour
The K650 is a fully automatic drying system for lettuce, fruit and vegetables and is designed for operation in continuous processing lines.
The product leaves the washing unit and is deposited on the infeed buffer conveyor. Due to the buffer conveyor, the K650 processes the product continuously, although the centrifuge itself dries in batches. As soon as the centrifuge with a 650 mm (25.6″)-diameter drum is full, the buffer conveyor runs in reverse mode until there is space in the centrifuge. With an optional volume control, the infed product quantity can be optimized. At the end of the drying cycle, the spinning speed is reduced and the product is gently forwarded to the discharge belt by a single blowing-off procedure. It is timed in such a way that the product flow is as even as possible. After drying, the product is transferred either into containers or onto the infeed belt of an automatic weighing or packaging machine. Without product, the unit automatically switches to energy-saving mode.
The K650 is supplied as a “Plug & Play” & version, meaning that only the cables of the individual components need to be connected in the switch cabinet to make the machine ready for operation. The switch cabinet is a free-standing unit and has a 10 m (32.8 ft) cable. The system is equipped with a TOSI-BOX for remote maintenance as standard. Optionally, the control unit can be upgraded with SMART functions.
For higher capacities up to 5,000 kg (11,000lb)/h, the upgraded K850 drying system is suitable.

Highlights

Compact design for a low space requirement
A total of eight different installation options (infeed from two directions and discharge in five directions) are possible for the K650. The system can therefore be flexibly integrated into existing systems in an extremely space-saving manner. With the infeed and discharge conveyors, it has a space requirement of 7,500 x 4,000 x 2,400 mm to 9,600 x 3,000 x 2,400 mm (295.3 x 157.5 x 94.5″ up to 378 x 118.1 x 94.5″) (LxWxH) during processing. The cleaning process requires 9,800 x 3,000 x 3,000 mm (385.8 x 118.1 x 118.1″) (LxWxH). The unit has been designed paying special attention to safety and does not require a safety zone or protective guards that would require a great deal of space and disturb working and cleaning procedures.

Simple, effective cleaning
The open and hygienic design ensures easy cleaning and maintenance. The system can be cleaned particularly quickly due to two optional cleaning modes, which adjust the speed of the belts and the machine. The cleaning mode when changing products is set using a key-operated switch. In the cleaning mode following the end of a shift, the machine runs until it has been completely pre-cleaned with water and sprayed with a cleaning agent. The cleaning mode is then switched off and the K650 and/or the belts are cleaned. The belts are mobile and easy to remove.

Flexible settings for a perfect result
In operation, a differentiation has to be made between two users: production and service. They have different access data to prevent settings from being accidentally changed. To ensure processing efficiency and the quality of the end product, various parameters can be set – depending on the consistency, shape and size of the product. The programs can be entered, changed and saved very easily using a seven-inch touch panel. Important parameters include the spinning speed and duration, as well as a right-left run mode for large-leaved products. Some parameters are automated, including the speed of the infeed and discharge conveyors, to make the system clearly structured and easy to operate.
