Description

Technical Field

[0001] The invention relates to the technical field of smoothie making, in particular to a sugar-free smoothie making system and a making method thereof. Background Art

[0002] In the existing technology, making smoothies is very common in daily life, such as in beverage shops or residents' homes. As people's demand for smart devices becomes more and more popular, how to improve the intelligence of smoothie making and to improve the final taste and production speed according to the different requirements of different drinks is an important research direction for continuously improving user experience in the future.

[0003] There are usually three methods for making ice smoothies in the prior art. The first is the physical crushing method of large ice blocks, which generally involves first freezing ice blocks of appropriate size, then crushing them, and then screening out ice particles of the desired particle size. It is not possible to continuously produce round ice particles, and the ice particles are easy to melt during the crushing and screening process. The second is the vacuum rapid cooling method, which requires a complex vacuum system, is not economical, and the temperature for generating ice particles is high, which is less practical. The third is the refrigerant direct contact freezing method, in which water droplets are easy to burst, and during the freezing process, the bonding phenomenon is serious. Although there are various ice particle production equipment and relatively mature technology, general ice making equipment requires large crushing machinery, has a complex system composition, is relatively large in size, has low ice particle preparation efficiency, and requires refrigeration.

[0004] The Chinese invention patent with the authorization announcement number CN107166831B discloses a continuous ice particle production device, including an atomizing nozzle, a swirl nozzle, an ice making chamber, a hollow tube, a hollow circulation nozzle, a mixing chamber, a pre-cooling chamber, etc. Water is atomized by the atomizing nozzle to generate water droplets, and low-temperature swirl gas is sprayed out through the swirl nozzle. The atomized water droplets are frozen to generate ice particles, and the low-temperature gas passes through the hollow circulation nozzle ice particles to further continuously prepare ice particles to produce ice particles. The swirl of the swirl nozzle and the hollow circulation nozzle, as well as the injection, entrainment and mixing effects, make the ice particles generate quickly, with uniform particle size and high strength. The pre-cooling chamber pre-cools and cools down, recovers cold, reduces and eliminates heat loss of low-temperature airflow, and saves energy. The system has a simple structure, small size, light weight, and low production cost. It can be used to continuously produce ice particles, such as ice particle jets in surface cleaning, rust removal, ice storage, and food processing.

[0005] However, the ice particle making device has a complex structure and is not suitable for daily use in a household.

[0006] Furthermore, in the prior art, in order to solidify liquid into smoothies, the viscosity of sugar is usually required to be utilized, and for sugar-free raw materials, since they are non-viscous, they need to be made into ice cubes and then crushed to form smoothies, which is extremely inconvenient for daily household use.

[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0023] like Figure 1 and Figure 2As shown, the following embodiments disclose a sugar-free smoothie making system and a making method thereof.

[0024] Example 1 like Figure 1 and Figure 2 As shown, this embodiment discloses a system for preparing sugar-free smoothies.

[0025] A sugar-free smoothie making system, comprising: The preparation container 200 has a raw material inlet 201 and a smoothie outlet 202, and is used for inputting raw materials 1 and outputting smoothies; The raw material container 100 is connected to the raw material inlet 201 of the preparation container 200 to provide the preparation container 200 with the raw material 1 required for preparing the smoothie; A cooling system, comprising at least one low temperature container 300, wherein the low temperature container 300 cools the preparation container 200 to keep the prepared material in the preparation container 200 at a low temperature; The preparation container 200 is connected to an air pump 400 via a pressure switch 500; The air pump 400 pressurizes the interior of the preparation container 200, and the low-temperature container 300 cools the preparation container 200, so that the raw material 1 in the preparation container 200 forms a high-pressure and low-temperature preparation material; when the preparation material is output from the smoothie outlet 202, it forms a solid smoothie at normal temperature and pressure.

[0026] The above is the basic solution of this embodiment.

[0027] Specific reference Figure 1 and Figure 2 As shown, in this embodiment, the raw material container 100 and the preparation container 200, and the preparation container 200 and the air pump 400 are connected through the conduit a.

[0028] The raw material container 100 contains ice-making raw material 1, which is preferably liquid, and can be sugar-free liquid such as water and green tea.

[0029] The raw material 1 in the raw material container 100 is input into the preparation container 200 through the conduit a and deposited at the lower end of the preparation container 200. The air pump 400 is turned on, and the air pump 400 pressurizes the preparation container 200 through the conduit a. At the same time, the cooling system works to cool the low-temperature container 300. The low-temperature container 300 absorbs the heat of the preparation container 200 and cools the preparation container 200. The cooling system and the air pump 400 work at the same time, so that the raw material 1 in the low-temperature container 300 forms a low-temperature and high-pressure preparation material.

[0030] When producing smoothies, the smoothie outlet 202 is opened, and the pressure of the low-temperature and high-pressure prepared materials is suddenly reduced at the smoothie outlet 202, thereby condensing to form smoothies.

[0031] The principle of preparing the smoothie in this embodiment is to change the freezing point of the raw material 1 by changing the pressure according to the different freezing points of the liquid under different pressures, so as to achieve the purpose of solidifying the liquid.

[0032] The freezing point of a liquid refers to the temperature at which the liquid begins to solidify under standard atmospheric pressure. However, the freezing point of a liquid is not always fixed and is affected by changes in pressure.

[0033] In this embodiment, taking liquid water as an example, the freezing point of water at room temperature is 0°C, but when the pressure is increased, the freezing point of water will be reduced accordingly, that is, the freezing point is below 0°C. In the preparation container 200, due to the cooling system and the air pump 400, the freezing point of the liquid water is lower than 0°C under normal pressure, and at this time the liquid water is in a low temperature state, but still higher than the freezing point under high pressure, so it is still in a liquid state inside the preparation container 200; When the ice smoothie outlet 202 is opened, the liquid water at the ice smoothie outlet 202 is suddenly exposed to the external normal pressure, causing the freezing point to rise, while the water temperature is still low. At this time, the water temperature reaches the instantaneous freezing point and solidifies to form ice smoothie.

[0034] In order to control the pressure in the preparation container 200, in this embodiment, a pressure switch 500 is provided on the conduit a connecting the air pump 400 and the preparation container 200. Different raw materials 1 have different freezing points. Therefore, the pressure value in the preparation container 200 can be set by the pressure switch 500 to achieve a pressure difference between the preparation material inside and outside the preparation container 200.

[0035] In this embodiment, the low temperature container 300 is filled with a coolant 2 .

[0036] The secondary coolant 2 is a substance that transfers the heat of the cooled object to the evaporating refrigerant in a refrigeration device working in an indirect cooling manner.

[0037] Preferably, in order to facilitate the circulation of the coolant 2, the coolant 2 can be water, salt water, ethylene glycol or propylene glycol solution, dichloromethane and trichloroethylene, etc.

[0038] During the process of preparing smoothies, the low-temperature container 300 needs to be continuously kept in a refrigerated state. Therefore, the refrigerant 2 in the low-temperature container 300 needs to be continuously replaced. In this embodiment, the cooling system also includes a refrigerant container 600, and a complete loop is formed between the refrigerant container 600 and the low-temperature container 300 through a pipeline for the refrigerant 2 to circulate.

[0039] The coolant 2 in the coolant container 600 circulates through the conduit a and the coolant 2 in the low-temperature container 300 , so that the coolant 2 in the low-temperature container 300 can continuously cool the preparation container 200 .

[0040] During the circulation process, since the refrigerant 2 absorbs heat from the preparation container 200, its own temperature will increase. Therefore, the heat absorbed by the refrigerant 2 needs to be discharged to ensure the cooling effect of the refrigerant 2. In this embodiment, an evaporator 700 is provided on the outside of the refrigerant container 600, and the evaporator 700 exchanges heat with the refrigerant 2 in the refrigerant container 600.

[0041] The evaporator 700 is a very important component among the four major parts of refrigeration. The low-temperature condensed "liquid" passes through the evaporator 700, exchanges heat with the outside air, and absorbs heat through "gasification", thus achieving the refrigeration effect.

[0042] After the refrigerant 2 in the cooling container absorbs the heat of the production container 200, it enters the cooling container 600 through the conduit a. The heat exchange caused by evaporation in the cooling container 600 dissipates the heat, so that the refrigerant 2 inside returns to a low temperature state, and then enters the cooling container through the conduit a to replace the refrigerant 2 that has absorbed the heat in the original cooling container.

[0043] In this embodiment, the evaporator 700 is filled with refrigerant 3 , and the evaporator 700 is provided with an inlet 701 and an outlet 702 for the refrigerant 3 to enter and exit.

[0044] Refrigerant 3, also known as refrigerant, is a working substance that continuously circulates in the refrigeration system and achieves refrigeration through its own state changes.

[0045] The refrigerant absorbs heat from the cooling medium (water or air, etc.) in the evaporator 700 and vaporizes, and transfers the heat to the surrounding air or water in the condenser and condenses.

[0046] The refrigerant 3 enters the evaporator 700 through the inlet 701 , absorbs the temperature of the cooling container 600 in the evaporator 700 , cools the cooling medium 2 inside, and is then output from the outlet 702 of the evaporator 700 .

[0047] Since different liquid raw materials 1 have different freezing points, and the freezing points vary inconsistently with changes in pressure, in this embodiment, a temperature sensor 10 is provided on the low-temperature container 300 .

[0048] The temperature of the prepared material in the preparation container 200 is controlled by the temperature sensor 10 , and different temperatures can be set according to different raw materials 1 to meet the requirements of forming smoothies with different raw materials 1 .

[0049] In this embodiment, a liquid level detection unit is provided in the preparation container 200 .

[0050] Specifically, the liquid level detection unit includes a high liquid level sensor 20 and a low liquid level sensor 30. The liquid level in the preparation container 200 is detected by the service detection unit to prevent the liquid level from being too high or too low, which affects the pressurization effect and causes the failure to prepare the smoothie smoothly.

[0051] In this embodiment, a first water pump 50 is provided between the raw material container 100 and the preparation container 200 to control the input amount of the raw material 1.

[0052] In this embodiment, the low-temperature container 300 and the cold-carrying container 600 are connected via a second water pump 40 .

[0053] When the liquid level in the preparation container 200 remains stable, the first water pump 50 is turned off, and the raw material 1 is no longer input. At the same time, when the temperature display on the temperature sensor 10 also remains stable, the second water pump 40 can be turned off so that the coolant 2 no longer circulates to ensure that the prepared material in the preparation container 200 is maintained at a stable temperature.

[0054] Example 2 This embodiment provides a method for preparing a sugar-free smoothie, which is applied to the sugar-free smoothie preparation system described in Example 1, and includes the following steps: S1, open the raw material container 100, and input the raw material 1 into the preparation container 200; S2, turning on the second water pump 40, and operating the cooling system to cool the preparation container 200; S3, the liquid level of raw material 1 reaches the set height, and the raw material container 100 is closed; S4, turning on the air pump 400, the air pump 400 pressurizes the raw material 1 in the preparation container 200, and the pressure switch 500 controls the pressure state in the preparation container 200; S5, controlling the circulation speed of the coolant 2 by controlling the second water pump 40 until the temperature of the temperature sensor 10 is maintained at the set temperature; S5, opening the smoothie outlet 202 to release the smoothie.

[0055] In this embodiment, step S3 and step S4 may be performed simultaneously or sequentially.

[0056] In this embodiment, in step S1, the raw material 1 in the raw material container 100 is a sugar-free liquid raw material 1; In step S2, the action of cooling the preparation container 200 can be performed before the input of the raw material 1, during the input of the raw material 1, or after the input of the raw material 1 is completed.

[0057] In step S4, the interior of the preparation container 200 is pressurized, preferably during or after the input of the raw material 1 is completed.

[0058] In addition, in this embodiment, the set pressure of the pressure switch 500 and the set temperature of the temperature sensor 10 can be pre-set according to the freezing point variation characteristics of the raw material 1.

[0059] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
