Abstract

<P>PROBLEM TO BE SOLVED: To circulate and introduce air having uniformly controlled temperature/humidity to bread dough in a baking oven chamber. <P>SOLUTION: This baking oven chamber 1 has a plurality of vertically arranged shelves 4, a dividing plate 6 installed at one side part of the shelves 4 and has an air hole 7 and a temperature/humidity controlling means 11 composed of a blower 8, a heater 9 and a steam generator 10. The air hole 7 of the dividing plate 6 is equipped with an air circulation circuit 12 that is laid between the shelves 4, has cross section areas successively increasing from a cross section area close to the blower 8 to a cross section area remote from the blower so as to suck air between the shelves 4 from the air hole 7 of the dividing plate 6 to the opposite side of the shelves 4 by operating the blower 8. The temperature/humidity controlling means 11 is arranged at the lower part of the baking oven chamber 1. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a proofing box for fermentation of bread dough.

  A conventional dough processing machine having a fermentation function is shown in FIG. This bread dough processing machine has the function of freezing, thawing and refrigeration in addition to the bread dough fermentation function. A shelf 34 on which a tray 33 in which a plurality of bread doughs arranged in the vertical direction are arranged in the storage 31 is placed, and a first ventilation path 37 formed by two partition plates 35 and 36 covering the back side of the bread dough storage. A second ventilation path 38, a heater 39 disposed in the second ventilation path 38, a blower 41 attached in the vicinity of the door 40 above the storage 31, and a machine room 42 above the storage 31 are configured. Yes. The partition plate 35 on the shelf 34 side is provided with a large number of air ejection holes 43. Further, as shown in FIG. 5, the number of the air ejection holes 43 is higher at the upper side than at the lower side, that is, the upper opening. The area is set to be larger than the opening area below.

When the fermentation function of the bread processing machine is activated, the amount of air blown from the air blowing holes 43 of the partition plate 35 from the first ventilation path 37 is blown more on the upper side than on the lower side. Further, since the air is ejected from the air ejection holes toward the bread dough, the air ejected from each air ejection hole 43 rapidly expands and diffuses at the moment of exiting from the air ejection holes 43 as shown in FIG. As a result, the air flow is separated and becomes turbulent. Accordingly, there is a defect that air that is uniformly temperature-controlled and humidity-controlled cannot be induced and circulated with respect to the bread doughs arranged in the plurality of trays 33 arranged above and below, and unevenness occurs in the bread dough.
Japanese Patent No. 2930461

  The problem to be solved is to circulate and induce uniformly temperature-controlled and humidity-controlled air to the bread dough in the proofer.

  The proofer of claim 1 of the present invention is a temperature control / consistor comprising a plurality of shelves arranged vertically, a partition plate having an air port arranged on one side of the shelf, and a blower, a heater, and a steam generator. Has humidity control means. And the air port of the partition plate is provided between the shelves, and the cross-sectional area of the one that is away from the blower is gradually increased, and the blower is operated to suck out the air between the shelves from the air port of the partition plate to the opposite side of the shelf. An air circulation circuit was provided.

  In the proofer of claim 2 of the present invention, temperature control / humidity control means comprising a blower, a heater, and a steam generator are arranged in the lower part of the proofer. Then, by operating the blower, air between the shelves was sucked out from the air port of the partition plate to the opposite side of the shelves, and an air circulation circuit from below to above was provided.

  The proofer of the present invention provides air between the shelves from the air port of the partition plate by providing air ports of the partition plates between the shelves and sequentially increasing the cross-sectional area of the one that is away from the blower and operating the blower. An air circulation circuit was provided on the opposite side of the shelf. Therefore, it is possible to make the air passage amount between the air ports between the shelves uniform, and the air on each tray is sucked out from the air port to the opposite side, so the air flow on each tray is not turbulent, and the temperature is uniform.・ It becomes a conditioned laminar flow (air flow). In addition, the temperature and humidity control means consisting of a blower, heater and water vapor generator are placed in the lower part of the proofing cabinet, so the temperature and water vapor rise naturally, making it suitable for natural providence, and temperature and humidity control. Maintenance of each device constituting the means is easy to perform.

  A description will be given using an example of the proofer of the present invention.

  FIG. 1 is a longitudinal sectional view of one embodiment of a proofing box according to the present invention. FIG. 2 is a front view showing an air port of the partition plate. FIG. 3 is an enlarged partial cross-sectional view of the air flow around the air port. 1 is a proofing warehouse. 2 is the body of the proofer. 3 is a door. 4 is a plurality of shelves arranged vertically. Reference numeral 5 denotes a tray on which the bread dough is arranged and is placed on the shelf 4. Reference numeral 6 denotes a vertical partition plate provided on the back side in the proofing box, and has an air port 7 having a cross-sectional area that is sequentially increased from the lower side toward the upper side. Each air port 7 is provided in the partition plate 6 so as to be positioned between the trays 5 on each shelf 4. 8 is a blower attached to the lower part of the partition plate 6. 9 is a heater arranged on the front side of the blower 8. Reference numeral 10 denotes a water vapor generator, which is disposed near the lower door 3 in the proofing box. The blower 8, the heater 9, and the water vapor generator 10 constitute a temperature adjustment / tempering means 11.

  Next, the operation of the proofer of the present invention will be described. Each tray 5 on which bread dough is arranged is placed on the shelf 4. Then, the temperature control / humidity control means 11 is operated by turning on a main switch (not shown). Then, the air on each tray 5 is sucked out by the blower 8 to the air circulation circuit 12 formed by the rear surface of the proofer and the rear surface of the partition plate 6 opposite to the air port 7 of the partition plate 6. The sucked air is warmed by the heater 9 disposed on the front side thereof through the blower 8, and further, an appropriate air humidity is obtained by the water vapor generating device 10 and the rear surface of the door 3 is raised while passing through each tray 5 and the air port. The air is optimal for fermentation of uniform bread dough circulated through the air circulation circuit 12 directed to 7 and adjusted in temperature and humidity. Thereafter, in order to maintain this optimum air, the inside of the proofer is kept at the optimum air for bread dough fermentation by an electronic circuit (not shown) that adjusts the operation of each device.

  It can also be used as a proofer other than bread dough.
