Introduction

PROBAT insists on sparing no effort in developing and manufacturing coffee roasting equipment and roasting plant technology. This is inextricably linked to PROBAT's goal of making every coffee bean at its peak.

We are proud of our decades of traditional experience and unique coffee roaster and processing equipment. Admittedly, due to the correct and in-depth understanding of roasting and grinding, we have made a non-negligible contribution to the charm of coffee. However, your knowledge and love endow coffee with its enduring charm.

We are honored that your technical and professional knowledge can be helped by the technical support we provide. It can be said that the baking technology we recognize should be: no matter what difficulties and limitations exist, we can try our best to meet your hopes and requirements.

Factory concept

Based on the in-depth study of the baking concept, today, our expertise makes the dream of providing customers with the overall design and installation of the baking plant a reality.

In the following content, you will see some pictures of PROBAT factory cases around the world.

Raw coffee bean processing system

CARRIER Series (receive)

Raw bean reception includes all the steps from the raw bean factory reception to the raw bean storage tank:

Raw bean receiving device

The raw bean receiving device can be packed in a single large bag, in the form of a 60kg / bag stacked on a tray, or even loaded in a super-large bag or in a container, or on a truck. No matter which form, the raw bean receiving system can handle it. You only need to choose different devices, either from the tray or from the truck, which are easy to unload. When all the transport bags are emptied, the quality of raw beans has been tested with reference to the sample. You can choose manual or automatic methods. At the same time, the water content of raw beans has also been detected.

CARRIER series (conveying)

Whether it is raw beans, cooked beans or coffee powder, coffee is transported from one place to another many times in the production process. In order to ensure the quality of the final product, the transportation link is very important.

According to the site conditions, Probat can design a customized transportation system. Customers can choose between mechanical transportation and pneumatic transportation.

Mechanical conveying systems are usually simple, but not flexible enough. Due to the modular construction and on-site construction, the condition cost of all construction sites is critical. Generally speaking, the investment cost of mechanical transportation is low. Especially the short and straight conveying path.

Pneumatic conveying is the transmission of products through high / low pressure. In principle, the transportation has been done in an airtight pipeline. The advantage of pneumatic conveying is that it is flexible, it is not limited by the site, and the working point can be increased at will.

CLEANER series

The raw beans received will inevitably be mixed with dust and various small and light solids such as sand, small metal devices, sack thread and so on, which need to be cleaned up.

CONTROLLER series

Before baking, some recipes need to be weighed in advance from different coffee storage tanks to mix a certain amount of raw beans, which we call formula weighing. The mixed raw beans are transported to the baking equipment through the pneumatic conveying system.

BROKER series

A typical silo-designed storage station is used to store roasted coffee beans. The storage station is a cylindrical multi-cavity structure, and all the cavities are distributed around the central axis.

The storage capacity of the multi-capacity cavity storage station is 1100 tons, depending on the size and number of products to be stored.

The distribution of rectangular silo containers is one by one, and the space is optimized, which is very suitable for large-capacity storage. Raw coffee beans and roasted coffee beans are stored in separate units according to different types.

The packing of the cavity uses a special device: a rotary tubular distributor with multiple outputs that can be distributed to one feed end.

ECOLOGIST series

Research and development background

Usually, the remaining heat from coffee roasting is discharged outdoors through pipes. In the baking plant, the exhaust gas temperature can reach between 320℃ and 860℃.

The body temperature mainly depends on the specific waste gas treatment unit. This energy has been discharged outdoors before it has been fully utilized.

Energy conservation and emission reduction has not only become an urgent task to save the growing energy costs and meet the increasingly stringent requirements of environmental protection, but also in line with the needs of economic rationality.

How to use the remaining energy cleverly?

On the one hand, the remaining heat can be reused in the baking process by using the heat exchanger, and it can also be used in other aspects (boiling water, heating).

However:

High maintenance costs for using heat exchangers

-not all the remaining energy used can be reused

-functions such as boiling water or heating are not required in summer

PROBAT has developed a preheating system for raw beans, which can be further baked using remaining heat.

The raw bean preheating system is connected with the upstream of the roaster, which does not need heating but can only be used in batch roaster.

Function description

With the centrifugal roaster model RZ... / 1-LT as an example (with thermal conductivity pre-cleaning function and coal contact function)

Gas supply

The pipeline system will extract the hot gas after waste gas treatment and purification and send it to the preheating bin.

Preheating

Preheat raw beans to a certain temperature in a preheating chamber (usually
