Next, an embodiment of an embodiment of the present invention will be described with reference to the drawings. Fig. 3 shows an example of the use of the heat insulation cover for the powdered dairy product when viewed obliquely from the front.

When the powdery milk product heat-retaining hippo-1 is used, for example, as shown in FIG. The pallet 21 having a rectangular shape in which the products are stacked (for example, 1500 mm on the long side and 1,300 mm on the short side) is not contacted with the periphery of the pallet 21 to enclose the entire side surface of the powdered dairy product in a four-sided upright wall shape.

Then, the upper side 1 f of the powdery dairy product heat-retaining cover 1 is covered with an upper cover 23 having substantially the same shape as the pallet 21. Thereafter, the tip ends of the pair of holding-side nylon belts 13 are inserted into the doughnut-shaped insertion portions 11a of the pair of holding-side nylon belts 11 and faced to the holding position 1d. Further, the magic tapes 9 on one end inside 1a and the other end outside 1b are bonded together. Then, the powdered dairy products stacked on the pallet 21 are stored in the space exposed by the pallet 21, the heat-retaining cover 1 for the powdered dairy product, and the upper cover 23.

Next, when the outside air becomes below freezing, the power cord 15 is connected to an external power source (not shown), and the planar heater 3 is energized. Then, the planar heaters 3 provided in the upper and lower two stages respectively generate heat and heat from the central portion of the three-layer structure of the heat insulating cover 1 for powdered dairy products to the outer space 17 and the inner space 19. Is diverged.

Then, as shown in FIG. 2, the heat radiated to the outer gap space 17 is prevented from moving to the outside air side by the heat insulating function of the heat insulating material 5 to which the high-vibe film mat is fixed on the outer surface. As a result, the heat is not taken away by the outside air, and the heat is trapped inside the outer clearance space 17. On the other hand, the heat radiated in the inner gap space 19 and the heat trapped in the outer gap space 17 are efficiently transferred from the entire inner length of the heat insulation cover 1 for powdered dairy products to the powdered dairy product side via the heat transfer member 7. Is transferred to. Also, cold air below the freezing point of the outside air tries to enter from the outside to the inside of the heat insulation cover 1 for powdered dairy products, but the entry is blocked by the heat insulating function of the heat insulating member 5 to which the high-foil mat is attached on the outside surface. To be done.

Then, in the powdered dairy product in which the entire length of the side surface is enclosed by the heat insulation cover-1 for the powdered dairy product, most of the heat generated by the planar heater 3 from the entire length of the side surface to the inside is generated. The heat is transferred and warmed, but the external cold air is not transferred. Therefore, powdered milk products such as powdered milk stored on the pallet 21 and stored in the space surrounded by the heat-retaining cover 1 for powdery dairy products and the upper cover 23 are kept warm and the water content does not freeze. The powder state is maintained and the product value is not impaired.

As shown in FIG. 3, an appropriate place on the outer surface of the heat insulating member 5 to which the high-foil mat is fixedly adhered to the outer surface (for example, the heat insulation cover-1 for powdered dairy products is the powdery dairy product as described above). A temperature controller 23 is provided at a corner portion where a worker can easily see when enclosing the four-sided upright wall. Then, in the temperature controller 23, an appropriate sensor for setting the heat generation temperature and heat generation time of the sheet heater-3 according to the degree of temperature decrease of the outside air temperature and detecting the temperature of the powdered dairy product. With a structure that works in tandem with etc., powdered dairy products such as milk powder are always stored at the optimum heat retention temperature, and the initial high commercial value is maintained without any loss of the slatted powder state or flavor. .

Further, since the heat-retaining cover 1 for powdered dairy products has a flexible strip shape, the entire length of the side surface of the powdered dairy products can be measured along an arbitrary outer shape of the pallet on which the powdered dairy products are stacked. Since it is enclosed in the shape of an upright wall, if the upper cover has the same shape as the pallet, the powdered dairy product can be stored without losing its commercial value in any storage form.
