Description

FILTER COFFEE MACHINE PROVIDING INDUSTRIAL SCALE PRODUCTION

Field of the Invention

The present invention relates to a coffee machine that enables brewing of different types of coffees in standard quality, adjusts temperature, process time and water flow rate parameters during the brewing process of coffee, provides serial, efficient and sustainable production with an industrial scale.

State of the Art

Filter coffee is usually preferred because it is a soft drink coffee product in which the taste and aroma of the coffee is more penetrating. The filter coffee brewing is mainly realized with the steps of adding hot water to the ground coffee and filtering the water over the coffee.

According to the daily requirements, it is used with different equipment such as French press, chemex, filter coffee machine, siphon, v60 etc. for brewing filter coffee. The duration, used product amount, filter temperature values used in the equipment in brewing cause differences in the taste and quality of the coffee.

The coffee machines used in the state of the art enables to brew coffee in a quantity that will only meet the needs in businesses such as cafes and restaurants, and in limited capacity at homes. The brewed coffee machines used in the state of the art are not industrial scale and their production capacity is very limited. The capacity of brewing in a batch is not sufficient for industrial scale brewed coffee and cannot fulfill the demand.

There are important parameters in brewing coffee depending on the coffee types. Parameters such as the type of coffee and appropriate temperature, process durations, flow rate of water, amount of water to be used, and coffee/water ratio are important for the taste and quality of the brewed coffee. These parameters are manually adjusted by the personnel in the production in the state of the art. This situation causes the production not to be made serially and the coffee in each batch cannot be produced with the same quality.

There is a determined process time in each production batch due to the brewing coffee production process depending on the type of coffee and product. A machine that performs brewing according to different coffee and product types and whose parameters can be changed is not available in the state of the art. The personnel is required to learn the duration of brewing and parameters specific to each type of coffee and in addition to this, is required to progress the process with different equipment suitable for production in the existing systems. Also this situation causes a limited production capacity. The processes must be continued at certain speeds and parameters so as to make industrial production.

Since the capacity of existing systems is insufficient, this prevents industrial-scale serial production; the waiting period causes increase in overtime and personnel costs depending on the nature of the process; it also risks the process efficiency and sustainability.

There is a patent application titled "AN ESPRESSO MACHINE" numbered TR 2017/18446 developed for espresso coffee making in the state of the art. This application relates to an espresso machine that operates with high efficiency, saves water and energy saving, can precisely adjust temperature and pressure settings. However, only a machine developed for espresso coffee making is disclosed in this method and this machine is not capable of producing with higher capacity.

On one hand, the essential difference between the production of espresso and filter coffee is that espresso is brewed at a high pressure; on the other hand, water moves slowly brewing between the coffee grains and is filtered into container downwardly by gravity in filter coffee. Therefore, the brewing process of filter coffee is longer and the parameters in its production are different.

As a result, novelty has been required for the inventive filter coffee machine providing industrial scale production, due to the insufficiency of production capacity and the absence of a system that can be able to control the critical parameters in production and the insufficiency of the solutions.
