WILIQIAMI H. PERRY, OF SAN DIEGO, CALIFORNIA.
DRYIN AIPPTUS.
Application filed May 10,
To all whom it may concern Be it known that 1, WILLIAM H. PERRY, a citizen of the United States, residing at San Diego, in the county of'San Diego and State of California, have invented certain new and useful Improvements in Drying Apparatus, of which the following is a specification.
My invention relates to a drying apparatus more particularly adapted for drying fish, fruit or vegetables by evaporation, more particularly by the use of a current of warm air for removing the natural moisture, from said fish, fruit, vegetables or other .articles and the objects of my invention are: first, to
provide an apparatus in which a currentv of air is circulated continuously through a fan and through a circuitous air duct containing a conveyor for the article to be dried and in which the moisture laden air is discharged at intervals as it passes along said conveyor laden with the article to be dried; second, to provide an apparatus of this class in which the air passing through and over the article to be dried will as soon'as it becomes sufficiently laden with moisture pass out and down through spaced apart apertures and the warm dry air pass to the intake of'the fan and through said fan and out again for use; third, to provide an apparatus of this class whereby the articles to be dried may be placed on the conveyor at one end and removed fromjthe conveyor at the opposite end and dried in itsmovement through the air duct through which the air passes in its circulations through the fan; fourth, to provide a new and novelly'contructed drying apparatus for de-hydrating fruits, vegetables, fish and the like; fifth, to provide an appara tus of this class which is very simple and economioai of construction and operation, very efiicient in its action and which will not readily deteriorate or get out of order.
With these and other objects in view as.
will appear hereinafter my invention consists of certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail and particularly set forth inthe appended claims reference being had to the accompanying drawings and to the characters of reference thereon which form a part of this application in which:
Figure 1 is a longitudinal sectional view through 1-.1 of Fig. 2; Fig. 2 is a top or plan view of the apparatus showing portions 1920.. Seriai no. 380,073.
broken away and in section to facilitate the illustration; Fig. 3 is a sectional view through 3-3 of Fig. 1 and Fig. 4 is a sectional view through 44 of Fig. 1.
Similar characters of reference refer to similar parts and portions throughout the several views of the drawings.
The casing 1, partition 2, heating pipes 3, fan 4, conveyor 5, sheave 6, support 7, support 8, sheave 9, and change speed transmission 10 constitute the principal parts and portions of my drying apparatus. The casing 1 is practically an air tight casng provided with a, partition 2 separating 1t into two air ducts A and B forming a continuous circuitous air passage. Mounted in the one end of this casing 1 is a fan 4, the casing being shaped to conform to the fan blades. The outlet of said fan communicates with the air duct A which is the outgoing air duct The inlet of'said fan communicates with one of the ends of the air duct B which is the incoming air duct so that the air circulates from the outlet of the fan 4 through the air duct A around the end of partition 2 and back through the air duct B to the intake at the side of the fan Mounted in these two air ducts A and B are pipes 3 which are heat conductors for either steam or air which are adapted to. connect with any air or steam suply so that the steam or air will circulate through these pipes for heating the air from the fan in its passage through the ducts A and B. Mounted longitudinally in the duct B and adapted to operate therein is the one side of a continuous formamincus conveyor 5 which passes through the casing 1 at opposite ends of the duct B through aperatures 1 and 1 The aperture 1 is provided with a slide door 1 adapted to regulate the size of the aperture 1 for regulating the quantity of air admitted from the outside to the fan inlet. In the lower side of the casing 1 below the air duct B are a plurality of apertures 1 which are adapted to permit the exit of moisture laden air from the duct B when it becomes sufficiently laden so that it will pass down through these apertures 1 as the air passes toward the inlet of the fan 4. The conveyor 5 is provided with any change speed mechanism for changing the speed of conveyor, the particular change speed mechanism bein no part of my present invention.
he operation of the dryer is as follows: The articles to be dried are placed on the upper side of the foraminous conveyor outside of the casing and passed through themcoming air duct B on said conveyor prefer ably in the same direction-as the 'air moves and it is intended that the conveyor should be regulated to travelat the proper. speed so that the articles onthe conveyor are dried intheir passage throu h the ducts B so they may be removed at t e other end of said duct after it passes out through the aperture 1 The air circulates continuously from the outlet of the fan over the heat pipes 3 around the end of the'partition'Q and back throu h the air duct B to the inlet of the fan. s a portion of the air becomes laden with moisture from the articles to be' dried it passes down-through the apertures 1 and to the outside and the aperture 1 is regulated to said apertures 1 thus the heated air is circulated continuously through the fan and released when the specific gravity becomes suflicient byreason of its becoming moisture laden to pass through said apertures I Though I have shown and describeda par ticular construction, combination and ar-- rangementof parts and portions I do not; wish to be limited to this particular construction, combination and arrangement-but V desire to include in the purview of my inbeing kept up near the entrance of the fan through the aperture 1 and that the air inlet may be regulated so that the amount.
of moisture in the air eliminated through the apertures may "be regulated dependent upon the quantity of natural moisture in the articles to be dried.-
Having thus described my invention what I clalm as new and desire to secure by Letters Patent is:
1. A drying apparatus including a casing provided with an outgoing and an incoming air duct and with a plurality of outlet apertures in its lower side and a foramiprovide for the loss of the moisture laden air which passes out through- Maaseo nous conveyor with onet side positioned in one of said air ducts and above said apertures. r
2. A drying apparatus, including a casing provided with a circuitous air duct, a foram-lnous conveyor with one side positioned in said air duct, the bottom of said casing I having a plurality of outlet apertures in the lower side of said air duct below said conveyor anda fan with its outlet communicating'with the outgoing portion of said air duct and its inlet communicating with the incomin portion of said air duct.
" 3. A drying apparatus, includin .a cas ing provided with an outgoing an incoming air duct, a foraminous conveyor with duct, the 'bottom of said casing having a plurality of outlet apertures in the lower one side positioned in said incoming air side of said casing below said conveyor, :1
fan with its outlet communicating with the outgoing air' duct and its inlet communicating with tlieincon'iing air duct'and means for admittingairinto said casing from the outside to the intake of said fan in regulated quantities. V v
4. A drying apparatus, includinga cas- Ting provided with an outgoing and incoming air duct, a foraminous conveyor with one side positioned in said air duct, the bottom of said casing having a plurality of air outlet aperturesin said casing contiguous to said conveyor, a fan with its outlet communicating withthe outgoing air duct and its inlet communicating with the incoming air ductand meansfor regulating the speed of said conveyor.
5. A drying apparatus,vincluding a casing provided with an outgoing and incoming air duct, a foraminous conveyor with one side positioned in said air duct, the bottom of said casing having a plurality of outlet apertures in the lower side of said casing below said conveyor, a fan with its outlet communicating with the outgoing air duct and its inlet communicating with the incoming air duct, means for admitting air into said casing from the outside to the intake of said fan in regulated quantities and means for regulating the speed of said conveyor.
In testimony afvhefeof, I have hereunto set my hand at San Diego,.California, this 1st day of May, 1920.
