Patenta& Oct. 31, 1944 UNITED STATES PATENT OFFICE" DEHYDRATOR. Elmo H. Williams, Altadena, Calif. Application August 9, 1943, Serial No. 497,961
8 Claims.
This invention relates to a dehydrator for the treatment of food and other materials` whereby moisture may be quickly and completely extracted or removed therefrom and at the same time bleach the material to a desired amount.
The primar-y object of the invention is the provision of a device of the above stated character which will be extremely economical to construct and operate and will permit the dehydration and bleaching of the material to be carried out in one operation and at the same time maintain a thorough agitation of the material to assure the rapid and complete dehydration thereof.
With these and other objects in View as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combinaton and arrangement of parts as will be hereinafter more fully described and claimed.
For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figura 1 is a vertical sectional view illustrating a dehydrator constructed in accordance with my invention.
Figure 2 is a top plan view illustrating the device.
Figure 3 is a horizontal sectional View illustrating the device.
Referring in detail to the drawing, the numeral 5 indicates a container, preferably more or less of bowl shape and mounted for rotation through the provision of a shaft 6 journaled in a hearing v 'l mounted on 'a support 8. The shaft 6 maybe belted or otherwise connected to a power source (not shown).
The container 5 includes a concaved rigid bottom or lower section 9 on which the shaft 6 is Secured. An inverted concave rigid upper section lo is mounted on the bottom or lower section 9 by a skeleton frame consisting principally of ve-tically arranged bars ll integrally connected with said sections 9 and ID. The rigid section o is superimposed with respect to the bottom section 9 and is spaced a selected distance therefrom. Also connecting the sections 9 and ID and to cooperate therewith in completing the container is a fiexible porous wall |2 preferably constructed of a suitable fabric and which is clamped in grooves !3 of said sections 9 and o by clamping rings M whereby the fabriomay at any time be removed for cleaning or forrenewal if worn or damaged.
The porous fiexible wall |2 rides against vertically arranged heating rolls l5 rotatably supported on the support 8. The heating of the rolls can be carried out in any well known manner,
preferably by electricity. The rolls' |5 have therein electric heating elements |5' and in order that they may be connected into an electric circuit, collector rings IS' are mounted on the rolls and are engaged by contacts IT' which may be connected in the electric circuit. In order that the rolls may be maintained at a selected temperature, the circuit may be controlled by a thermo apparatus of a conventional type,
The wall !2 when in contact with the rolls will be fiexed inwardly, a clearly shown in Figures 2 and 3 and the fiexing of the wall as specified besides the rotation of the container, will bring about a complete agitation of materials arra'nged therein and in order that an air circulation may be had within the container during the rotation thereof the upper section ID is provided with a series of struck-out blades IE and ports ll ad- -jacent thereto. i Further, the upper section n is provided centrally thereof with a neck l8 extending inwardly of the container and centrally thereof. This neck provides an air escape while the air will be drawn in through the ports I 1 by the blades IG during the rotation of the container, Contacting the material within the latter to thoroughly aerate the material. The air after Contacting the material escapes by way of the neck l8. The upper rigid section ll] of the container includes detachably connected parts clearly shown in the drawings, whereby one part may be easily removed to permit material after being treated in the device to be easily removed therefrom. i
In operation, the material to be dehydrated is cut or chopped into small piece or ground and then placed within the container by way of ,the neck !8. The container is then rotated by the power medium (not shown) and during its rotation the material is thrown out against the wall I2 by centrifugal action and as the wall is engaged by the heating rolls' the mosture of the,
due to the novel way of subjecting the material to heat for converting the moisture into steam and carrying ofl of the steam by the circulation of air into and from the container.
Due to the constant movement of the material with relation to the heating rolls will allow extremely high temperatures to be employed without the danger of' scorching the material and which results in a more rapid extraction of the moisture from the material. Also, the novei agitation of the material during the heating thereof greatly assists in the rapid extraction of the moisture.
While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in Construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.
Having thus described my--invention, what I claim is:
1. In a dehydrator, a container `for materials, means for the rotation of said container, said container having fiexible porous portions engaged by the material by the rotation of the container, heating means engaging said porous flexible portions to convert moisture in the material into steam, and means for circulating air ,into and out of said container for carrying off moisture from the container.
