Description

Milk boiler heater for coffee machine

Technical Field

The invention relates to the field of electric heating pipes, in particular to a milk boiler heater for a coffee machine.

Background

In the beverage menu of a coffee shop, milk and espresso are "soul elements" that make up most of the beverages. The addition of milk to coffee began in the 16 th century and although we could not trace back how it started, the delicious effect could not be denied. By now, most consumers will choose cappuccino, latte or other milk coffees when they first contact coffee, so milk coffees are a door to the world of fine coffee for many people.

While milk added to coffee is mainly made in two ways: foamed milk and hot milk. In either case, the milk is heated in a refrigerated storage. The current mainstream heating mode is that high-temperature steam is adopted to directly heat milk, and only one cup of milk can be heated at a time. And the steam contains a certain amount of moisture, and condensed water generated by the moisture enters the milk, so that the mouthfeel of the milk is reduced.

Disclosure of Invention

The invention aims to solve the technical problem of overcoming the defects in the prior art and provides a milk boiler heater for a coffee machine.

In order to solve the technical problem, the technical scheme adopted by the invention is as follows:

a milk boiler heater for a coffee maker is provided, including a boiler and an electric heating tube. The milk boiler comprises a boiler barrel, a boiler lower cover is arranged at the bottom end of the boiler barrel, a flange cover is detachably connected to the top end of the boiler barrel, and a plurality of holes are formed in the flange cover; the electric heating pipe is arranged at the bottom in the boiler, the end part of the electric heating pipe penetrates out of the lower cover of the boiler and is connected with the power supply connecting sheet, and the milk pipeline component is arranged at the upper part in the boiler; the milk pipeline component is a spiral coil pipe, the spiral coil pipe is fixedly connected to the flange cover through a fixing component, and pipe bodies at two ends of the spiral coil pipe penetrate through holes in the flange cover to reach the outside of the boiler; the temperature control accessory flange, the water inlet flange and the water temperature detection accessory flange are arranged on the hole of the flange cover.

As an improvement, the lower cover of the boiler is welded with the boiler barrel.

As an improvement, the fixing component is a hoop.

As an improvement, the outer side wall of the boiler barrel is provided with a mounting bracket.

As an improvement, the lower end face of the lower cover of the boiler is provided with a grounding sheet.

As an improvement, the outer side wall of the boiler barrel is provided with a temperature controller mounting stud for connecting a temperature controller.

As an improvement, a sealing O-shaped ring is arranged between the boiler barrel and the flange cover.

As an improvement, a sealing O-shaped ring is arranged between the pipe body at the two ends of the spiral coil pipe and the opening of the flange cover.

The principle of the invention is as follows: the milk boiler heater is characterized in that cold milk in a pipeline with a smaller inner diameter is heated by adopting a water bath heating mode, hot milk meeting a target temperature is continuously obtained, and no other water is added in the heating process of the milk. And when the milk is heated to more than 40 ℃, moisture is evaporated from the liquid surface continuously, milk fat and protein are separated out and are easy to attach to the inner wall of the pipeline. In order to ensure the smoothness of the milk pipeline and the heating efficiency, the milk pipeline is fastened on a flange cover of a boiler heater in threaded connection through a hoop, and a new milk pipeline component can be replaced periodically.

Compared with the prior art, the invention has the beneficial effects that:

the electric heating pipe in the boiler preheats the water in the boiler to a certain temperature at present, and cold milk passes through the pipeline of less internal diameter (2.5mm) according to certain velocity of flow, and hot water in the boiler lasts the heating to the milk in the pipeline, can realize going out hot milk in succession. Meanwhile, the milk pipeline assembly is replaceable, so that the phenomenon that the whole milk boiler heater fails due to the fact that the pipeline is blocked by components such as fat in milk is avoided, and the maintenance cost of equipment is reduced.
