DTI-1225 Drop Bottom Batch Oven
Customer directive
Our customer wanted to create an indexing single part flow inert atmosphere production furnace system to match, and seamlessly integrate into, the customer’s entire existing manufacturing process at a production rate of 45 seconds part to part. The customer’s then existing process included inefficient batch furnace staging of parts at this point in the process.
Description
The DTI-1225 drop bottom batch oven is used to process titanium parts. The system utilizes a rack system that lowers into and out of the oven. When the rack is in place it becomes the floor of the oven. Product is loaded onto the rack and the control switch in engaged raising the rack and placing the product in the heated chamber. At the end of the heating cycle the rack is lowered and the product is unloaded from the rack and a new product is placed on the rack. Once the new product is in position the cycle repeats.
There is approximately five (5) minutes between cycles for loading and unloading product. The airflow in the ovens heated chamber is a horizontal cross flow. However, the plenum system features a by-pass duct system that keeps heated air from entering the heated chamber while the drop bottom is lowered and being loaded with product. Additionally, the burner system automatically goes to a low fire setting when the drop bottom is lowered. Both of these features ensure that the oven is operating as efficiently as possible.

Features
Drop Bottom Batch Oven Construction Features
Due to the corrosive nature of the product this oven utilizes stainless steel for the structural steel frame, oven interior and oven exterior. Other features include, but are not limited to, the following:
- The interior seams of the oven chamber are seal welded to prevent corrosive by products of the process migrating into oven walls and insulation.
- One (1) Circulation Fan
- One (1) full modulating natural gas burner system
- One (1) exhaust fan
- One (1) access door provides access for maintenance and cleaning of the heating plenum and meets NFPA explosion relief requirements.
- The oven utilizes 10” thick insulated walls
- A structural steel base frame ensures the elevation of the heated chamber is 7’-0” above the finished floor.
- The oven is constructed in two sections to accommodate shipping and installation requirements.
