Abstract
A particulate material heater consisting essentially of an elongated housing consisting of an outer shell having at least one wall, a first end and a second end. The first end is movable into and out of the housing, and the first end has an opening through a front wall of the first end. There is a heating unit housed in the housing. The heating unit has electrical energy supply conduits from the heating unit to en electrical power source in one embodiment. In addition, the material heater can have a unit for controlling the energy input to the heater.

DETAILED DESCRIPTION OF THE INVENTION
[0033] Turning now to
[0034] The first end 5 is removable from the opening 6. A handle 7 is fixedly mounted on a front of the first end 5 for purposes of handling the first end 5.
[0035] Referring to
[0036] Turning now to
[0037] Number 14 designates the general electrical connections and wiring for the thermostat 9, the heating element 13, the limit switch 10 and the like.

[0045] The overall length of the heater is about 2 to 6 feet, while the width of the heater is on the order of about 10 inches to about 18 inches. The overall height of the device 1 is on the order of about 12 to 18 inches. The devices are manufactured from metal and it is contemplated within the scope of this invention to use steel having a gage in the range of about 11 to 16, or less depending on, the type of steel used.
[0046] The electric heater used in this invention is contemplated to be a heater that has 1250 watts and operates between 60 to 360° F. Such a heater can be, for example, a finned strip heater sold by ZORO, WWW.ZORO.COM.
[0047] In use, the device 1 is place on the ground or a trailer and the thermostat is set to the desired temperature. Sand or other particulate material is dumped over the heater and heated. In use, the device 1, and the sand, can be covered with an insulated blanket or cover. Using the Zoro heater, a pile of sand can reach about 1220° F. over a short period of time.
[0048] Although the description has been generally based on the use of electrical energy to heat the device 1, it is contemplated within the scope of this invention to heat the device 1 using any type of heating element inside or the housing, such as a finned heater element, tube element, infrared element or oil fueled element.
EXAMPLES
Example 1
[0049] Two yards of mason sand were dumped onto a trailer over a device of this invention. The heater was set at 150° F. The trailer temperature was 24° F. and the sand temperature averaged over the pile to be 25° to 28° F. The overnight temperature was 22° F. with a wind chill factor of 18° F. After 12 hours, with an insulated tarp covering, the sand, the temperature was 49° F. at the top of the sand pile, and the temperature was 90° F. in the middle of the sand pile.
Example 2
[0050] During the winter of 2014/2015, a heating device of this invention was located under 10 yards of mason sand and the thermostat was set at 250° F. and the sand pile was covered with an insulated tarp. The heater was used non-stop from Dec. 14, 2014 to Feb. 16, 2015 and the sand pile was thawed and warm all of this time showing that the heater of this device is efficient and low cost.
