Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides flavor, shape, and
This relates to a hot food preservation vehicle for storing and transporting hot food without changing its quality.

A system that preserves foods that are meant to be eaten hot after production and delivers them to customers as is has been realized by minimizing the distance and time required for transportation. Specifically, almost all restaurants are built on a structure that brings the kitchen and customer seating into close contact.

The present invention enables transportation and storage over long distances and long periods of time by storing and transporting hot foods in a hot food storage warehouse, thereby reducing the distance and time of spatial movement of hot foods.

The theory of passurization, which states that "most of the spoilage bacteria are killed and sterilized," was known early on in the food industry as a pasteurization method and has been applied to sterilize milk and beer. However, this theory has hardly been applied to general foods. This is because conventional hot storage systems are either dry heat type, which only provides heat, or steam type, which generates unlimited steam and also provides heat, so it is important to consider the preservation of food under bus tourism conditions. The performance was just unsuitable.

Food is stored in a dry-heat heating cabinet, and the core temperature of the food is kept at 63℃.
If the temperature of the retainer exceeds ℃, the food will dry out and deteriorate in a short period of time.

Furthermore, if food is stored in a steam-heating refrigerator at a temperature of 9-7 degrees, the absolute humidity inside the refrigerator will be extremely high, resulting in most of the food becoming soggy. To avoid this, lower the storage temperature to around 40℃.
We are taking measures such as shortening the detention time as much as possible,
This encourages the growth of bacteria, and people have come to believe that it is better to keep things warm, rather than storing them in warm storage.

The present invention is a food warming refrigerator that has a function of maintaining the temperature and humidity inside the refrigerator at a preset temperature and humidity while measuring the temperature and humidity inside the refrigerator, which is a part of the truck body. The on-vehicle heated food storage is a movable model that can be loaded onto a truck or dried into hot food.
Supply, without any changes such as deterioration or softening.
It is possible to donate.

Even if a sales case, heating cabinet, etc. that has the function of measuring temperature and humidity and adjusting and maintaining them at the set values is installed at the sales point to sell food in a warm state, the difference between the production location and the sales point. The longer the distance, the more the food will be cooled during transit, and by the time it is placed in the sales facility,
It may happen that the food has cooled below the temperature.
) If there is no guarantee that the Z Snow Rise Noyon conditions are met and that bacteria due to secondary infection during cooling are re-sterilized, the seller cannot sell to customers the food that has been sterilized using the Bus No Rise Noyon. It takes a surprising amount of time to reheat food once it has cooled in the refrigerator to bring the temperature at the center of the food back to 63°C.

Figure 1 shows that when a single serving of eel rice that has been cooled to a core temperature of 5°C is stored in a heating cabinet whose internal temperature is set and maintained at 65°C, the ID temperature inside the food is 65°C. 2 is a graph showing the relationship between the center temperature and time until the food reaches 45° C. and saturates with the ambient temperature. FIG. 2 is a similar graph when the food is stored in a hot storage at a center temperature of 45° C.

For sterilization, it is essential to maintain the temperature for at least 30 minutes after the core temperature exceeds 63°C, so in both cases, the completion time for sterilization is 135 minutes after storage. . Therefore, the product cannot be sold as a food product for 2 hours and 15 minutes after being stored.

In order to eliminate this inconvenience, it is necessary to maintain the core temperature of the food at 63° C. or higher throughout the entire period from production to sale, and to prevent deterioration of flavor, shape, and quality.

According to the present invention, manufactured hot foods are stored as they are in an on-vehicle hot food storage warehouse, transported to a sales point, and stored in sales equipment. can be sold without deterioration or alteration.

The present invention provides a heated food preservation warehouse having a heating and humidifying function that measures and controls the temperature and humidity inside the heated warehouse and maintains the internal conditions at arbitrarily set temperature and humidity in advance. This is an in-vehicle ambient temperature food storage that can be moved by making it a part of a truck or loading it on a truck. The heating heat source may be an electric heater, combustion of combustible material, radiator water of enodine, waste heat measurement of exhaust gas, etc., and the humidification method may be a known method such as steam or spray.

Figure 3 is an example of an electric circuit that controls the temperature and humidity of a car-mounted ambient temperature food storage.When the power supply is connected to a 200V single phase and the non-fuse breaker (NFB) for the power supply is turned on, The water level warning buzzer (BZ) issues an alarm,
The water supply valve (BV) automatically opens and starts pouring water into the humidifier (heater 3). During this time, the pilot lamp (Pl) for the lunoid valve circuit lights up. At the same time, the fan for cooling the control section (FA, 1) and the fan for forced circulation of air inside the refrigerator (FA2) start rotating.When the water level in the humidifier (heater 3) is filled, the water level alarm buzzer (BZ) stops and the water supply starts. Set the solenoid pulp (Bv) to an arbitrary value.

Main switch (Ms, 1. Heater switch (Ms)
2) and the humidifying heater switch (Ms3) are turned on, the heaters 1, 2, and 3 are energized, the heater circuit nokue/tramp (F2) and the humidifying heater circuit pilot lamp (F3) light up, The temperature and humidity inside the refrigerator begin to rise.

When the temperature and humidity inside the refrigerator rise and the temperature measurement value by the temperature sensor (TM) for measuring the temperature inside the refrigerator or the humidity measurement value by the humidity sensor (TH) for measuring the humidity inside the refrigerator reach their respective set values, The relay of the heater switch (Ms2) or humidifying heater switch (Ms3) is turned OFF by the temperature control meter box or humidity control meter box, and the electricity to the heaters (1, 2) or humidifier (heater 3) is cut off. . Temperature sensor for internal temperature measurement (T
H) If the measured value of each sensor (TM) for the chamber humidity meter side falls below the respective set value, the heater switch (Ms2) or humidifying heater will be automatically turned on according to the temperature control meter ■ or humidity control meter diagram. switch(
Ms3) Norin is turned on and power is applied to the heaters (1, 2) and the humidifier (heater 3).

When the water level in the humidifier (heater 3) falls below a predetermined level, the float switch (OL) operates, opens the water supply solenoid valve (BV), and water flows into the humidifier (heater 3) until the water level is filled. When the water supply lunoid valve (
BV) is automatically closed by a float switch (OL).

By constantly and automatically performing the above-mentioned functions, the temperature and humidity inside the refrigerator are always maintained at the set values.
