I'm new to Openbuilds and linear actuators and am seeking feedback regarding a solution that I have in mind. I am currently using a steam tray (roughly 20 x 13 inches and 4 inches deep) as a chocolate dipping pot for products that I manufacture. The tray is maintained at 95-degrees F to keep the chocolate in a liquid state. When not in use, the chocolate needs to be slowly stirred/agitated to prevent formation of clumps. I believe that a paddle attached to a linear actuator would provide the back and forth motion that I am seeking. The requirements of the project are as follows: Motor must not be over the chocolate: left or right side of the gantry. A belt driven gantry seem preferable to screw for sanitary purposes Paddle must be able to detach from the gantry for ease of cleaning Gantry should travel the length of the tray in roughly 30 seconds, then reverse direction and travel back in roughly 30. Total back/forth travel time is 60 seconds. Programmable on/off time would be nice. Continuous stirring is not needed. For example, 5 minutes of stirring per hour would be sufficient. This would also give the motor a rest. The paddle would be roughly 20 inches wide, by 3 inches tall and made of thin stainless steel. Holes would drilled into so chocolate can pass through easily. Thus, resistance will not be very high. Some sort of slip clutch or overload shut off would be helpful to protect the motor in the event that the heating element fails and the chocolate solidifies. The solution should be easily removed from the tank and set aside so that product can be dipped into the tank. Thus, ease of mobility and light weight is important. Suggestions would be appreciated regarding available kits that are best suited for this application. Also, suggestions for controllers, limit switches, motors, gantry arm styles, etc. would be appreciated.
