Drink preparation device

Abstract

The invention discloses a drink preparation device, belonging to the field of machinery. The drink preparation device is mainly used for blending overheated hot water in a hot water pipe with cold water of a set flow rate in a cold water pipe to form a blended water flow with suitable temperature, and transmitting the blended water flow into a liquid dispenser. When a brewing solenoid valve is controlled to be opened, the liquid dispenser dispenses the blended water flow with suitable temperature to a preparation container in which drink components are previously provided so as to prepare drink from the drink components; and when the brewing solenoid valve is controlled to be closed, the liquid dispenser dispenses the blended water flow with suitable temperature to a hot water feeding pipe, and the blended water flow with suitable temperature is directly fed into the drink when a hot water feeding solenoid valve is controlled to be opened. When the brewing solenoid valve and the hot water solenoid valve are both closed, the hot water in a heat exchanger volatiles, passes through a preheating circulation line, and returns to a heat exchanger after being preheated by the liquid dispenser so as to form a preheating circulation.

Description

technical field [0001] The invention belongs to the field of machinery, and relates to a beverage preparation device, in particular to a beverage preparation device capable of preparing beverages with different temperatures and concentrations. Background technique [0002] Beverage preparation devices are used for brewing coffee, tea or other beverages. Such as Figure 17 The shown existing beverage preparation device mainly includes a water supply pump 80 , a main boiler 81 , a heat exchanger 82 and a liquid distributor 83 . Use the water supply pump 80 to supply external water source to the main boiler 81, and a water level detector 84 controls the opening and closing of the water supply pump 80 and the boiler water inlet solenoid valve 95, so that the water level in the main boiler 81 is maintained at Within a set range; use a steam pressure detector 85 to control the opening and closing of a heater 86, which is used to heat the stored water in the main boiler 81 to keep...

AI Technical Summary

Problems solved by technology

Although the existing beverage preparation device can be equipped with two or more groups of liquid dispensers and preparation containers, its hot water supply system can only supply hot water of a single temperature to each liquid dispenser and preparation container for beverage brewing process, so It can only be pre-set to brew the same type of beverage, which can be called a single-product beverage preparation device; for practitioners with different types of beverage market needs, it is necessary to purchase multiple single-product beverage preparation devices with different settings. The product beverage preparation device is used to brew different types of beverages, which not only increases the equipment purchase cost of employees, but also has the disadvantages of inconvenient operation and low equipment replacement rate
