Walk-In Ovens and Truck-In Ovens
Despatch walk-in and truck-in ovens can accommodate a variety of specific product and process needs. These
ovens are suitable for loading manually or by fork truck. Typical applications include: aging, bonding, curing,
drying, baking, heat treating, annealing and stress-relieving. Despatch’s design, manufacturing, quality and
innovation ensure industrial ruggedness, excellent process control, and dependable operation.
Custom Walk-In Ovens and Truck-In Ovens
Vial Seal Cap Curing Oven
A pharmaceutical manufacturer needed a reliable oven to heat cure the seal caps on vials. A customized Despatch
TA truck-in and walk-in oven offered the ideal thermal curing solution and allowed product to be loaded and
unloaded directly into and from the oven with minimal material handling.
This customized TA truck-in and walk-in oven featured a stainless steel interior
and exterior to meet the customer’s application. The oven also features a high volume
recirculating fan with horizontal airflow for fast, uniform heating. The
Protocol Plus™ controller ensures accurate temperature and process control.
The TA truck-in and walk-in oven is shipped fully assembled, wired and tested
to minimize installation time.
Dual-Chamber Heat-Curing Oven
An industrial equipment manufacturer needed an oven to both heat-cure
and store sheets of material at different temperatures in a single oven.
Despatch designed a custom TA truck-in and walk-in oven with an insulated horizontal center panel to separate
the oven interior into upper and lower chambers, each capable of different processing temperatures. Despatch
provided upper and lower racks with shelves for fast, efficient product loading and unloading.
Additional fresh air inlets with manual dampers were installed in the lower
chamber to allow the chamber to operate 10-20°C cooler than the upper
chamber. Adjustable louvers in the chambers provided temperature uniformity
throughout each chamber. An additional thermocouple with digital readout
was added to monitor the lower chamber temperature.
Custom Thaw Chamber
Despatch developed a highly uniform, custom thaw chamber for the
pharmaceutical application of thawing bags of frozen liquid under very
controlled conditions. The precise thawing technology uses high speed horizontal airflow in a closed chamber to
thaw batches as quickly as possible while maintaining uniform temperatures in
each individual bag. Utilizing a thaw chamber instead of a customary water bath
eliminates the possibility of the bags cross-contaminating from any leakage.
Custom Trucks and Carts
Products may be moved into and out of ovens by a wide variety of material
handling equipment. Despatch can engineer custom truck solutions from
simple manual systems to complex automated systems. For a truck loaded
oven, you need to consider how many products can be loaded on the truck,
the weight of the loaded truck, number of trucks that will fit in the oven, and the length of the process time in the
oven. Trucks and carts can be designed to optimize the airflow pattern of
the oven around the load. The main goal is to minimize obstructions to the
airflow for more uniform heat distribution and to maximize the product surface
area with which airflow will come into contact.
Billet Mixer: This specially designed
truck with automatic engagement to
a rotating drive is for warming various
plastic pellets to be used in injection
molding processes. The rotating cart
keeps the pellets from sticking together
while at temperature.
Filter Drying Cart: This special truck is designed for curing and drying of
various liquid filters of similar diameters but a large range of lengths. The
design allows for large quantities of varying sizes to be processed at the
same time. The removable slats that the vertical tubes are on provides for
large quantities of varying sizes to be processed at the same time. The
removable slats that the vertical tubes are on provides for added flexibility.
