PATENT OFFIGE.

APPARATUS FOR MALTING CEREALS.

SPECIFICATION forming part of Letters Patent No. 254,374, dated February 28, 1882.

Application filed March 10, 1881. (No model.) Patented in France March 15, 1880.

To all whom it may concern:

Beitknown that I, JULIEN PUVREZ, ofLille, France,.have invented a new and useful Improvement in Apparatus for Malting Cereals,

of which the following is a specification.

This invention relates to certain new and useful improvements in apparatus for germinating and drying malt, whereby the malt is obtained in a better state in a much shorter to time and more economically than with the devices in use at present.

These improvements will first be described in connection with the drawings, and then pointed out in the claims.

In the accompanying drawings, Figurg is a plan view of my improved malt-chamber, sho'win g the several modifications of the germinating and drying floor. Fig. 2 is a longitudinal sectional elevation of the same. Fig. 3 is a cross-sectional elevation of the same. Fig. 4 is a longitudinal elevation of the refreshing and moistening chamber ofm y improved malthouse, showing parts broken out to show the construction.

2 5 Similar letters of reference indicate corresponding parts.

The floor of the malt-chamber A is about five to six inches above the ground, and is formed of a series of strips, B, of wood. and

perforated metal strips B which are arranged alternately, as shown in Fig. 1. The advantage of this alternate arrangement of wooden and metallic strips is that it prevents a too rapid distribution of heat, and prevents the 3 5 malt from being two quickly heated.

A ventilating-chimney, G, is located at the end of the ventilating-channel, and is provided with a small furnace for creating a draft. The walls D of the ventilating-channel E are pro- 0 vided with apertures I, which increase in size from that end of the channel E provided with aventilating-chimney, G, toward the other end, for the suction is much greater at the end near the chimney, and therefore smaller apertures 5 I will answer at this end.

The steeped grainis placed upon the floor of the malt-chamber, about twelve to fifteen inches high, and the ventilating or drying air passes through this layer of grain and through the slots or perforations in the floor of the maltchamber, and then passes through the apertures I in the ventilating-channel E and the chimney G, as is indicated by the arrows. But it is necessary that the ventilating-air that passes into the malt-room shall be moist and fresh-that is, contain a quantity of ozone and for this reason one or two moistening and refreshing chambers, J, are arranged at the end of the malt-chamber opposite to the ventilating-chimney G. A water-tube, K, with small perforations on top, passes through the top of the chambers J, and through these per forations of the tube K the water spouts upon a plate, W, directly above the tube K, where by the water is atomized and converted into 6 spray. From this plate, W the water runs down a series of strips otcloth or linen, M, suspended from a frame, L. These strips of cloth may be replaced by linen sheets or pieces of cord or rope. From the lower ends of these cords, ropes, or sheets M the water drops upon a quantity of sp0nges,N, on a perforated shelf, 0, in the bottom of the chamber J, and from this shelf the water drops upon the sponges N on the next lower shelf, 0, and so from one shelf upon the oth er; The water is thus spread upon a vast surface, and the air which enters the chamber J through the bottom aperture, P, and leaves it through the upper aperture, P, will be saturatedwith moisture when it enters into the malt-house through this upper aperture, P; but the air will not only have absorbed moisture; it willalso be slightlyimpregmated with ozone, and will be cooled. Cooled fresh air which is moistened and is ozonized greatly facilitates the germinating of the cereals.

The moisture-chambers J are provided with vertical openings Q, extending from top to bottom on the front side, and these openings 0 are closed by means of sliding or swinging shutters Q. These openingsare provided to permit the quantity of sponges and the strings or strips M to be regulated and keptin proper order.

A portable sheet-iron stove, B, which is covered with some non-conducting material, can be connected with the malt-chamber for partially drying the malt in the same room in which it is germinated. This stove R is provided with a perforated horizontal plate, S, some distance above the fire, to prevent sparks and cinders from entering into the malt-room. As malt requires a certain quantity of fresh air while drying, an aperture, T, is provided in the stove directly above the plate S, and through this aperture the fresh cool air enters.

A series of plates, U, are suspended verti cally in the upper part of the stove 1t, and as the cold and hot air pass up between these plates, they will be subdivided into so many layers, and will be thoroughly mixed above these plates. The warm air from the stove It also enters into the malt-room on top.

The operation in the malt-germinatingchamher is as follows: The steeped grain is placed upon the perforated or slotted floor of the malthouse A, about twelve to fifteen inches deep. The air passes into the moistening-chamber J at P,passes into the malt-germinating chamher at P through the moistened grain, through the apertures ll into the channel E, and up through the chimney. After the grain has germinated sufficiently,which, according to circumstances, may require from six to ten days, it is brought into the kiln to be dried.

I am aware that a malting apparatus has been provided with a perforated bottom in the malt-chamber, a ventilating-channel beneath it, a Yentilating-chimney at one end, and a' moistening-chamher at the other end of channel; but

WhatIclaim as new,and ofmyinvention,is--

1. -In a malt-chamber, the floor constructed, substantially as herein shown and described, with alternating strips of wood and of perforated metal, as and for the purpose set forth.

2. The moisture-chambers J, provided with vertical openings Q, extending from top to bottom on the front side, whereby the sponges may be regulated, as described.

3. In a malt chamber, the combination, with the air refreshing and .moistening chamber, of the perforated tube K, and of the atomizingplate W arranged above it, substantially as herein shown and described, and for the purpose of atomizing the water, so that the air that passes through the chambers J J will be slightly impregnated with ozone.

4. In a malt-chamber, the combination, with the air refreshing and moistening chamber, of

the water-tube K, the atomizing-plate W, the

cloth strips M, and the sponges N, substantially as herein shown and described, and for the purpose set forth.
