About the roasting processing line
About roasting processing
The main reasons why “roasting” is chosen as a heat treatment method are ‘aroma’ and "flavor improvement.
Roasting at high temperatures produces a browned and aromatic flavor.
We offer three types of roasting processes: hot-air roasting, sand roasting, and open-flame roasting, which have the following characteristics.
| Roasting machine | Roasting method | Feature |
|---|---|---|
| Hot air roasting machine | 【Continuous and batch type】 Roasting is done by hot air generated from the burner. |
・Heat control is possible ・Low risk of foreign material contamination |
| Direct-heating roasting machine | 【Batch Type】 Roasting by direct fire. |
・With the unique flavor of direct fire ・Only hard roasts can be produced due to low heat |
| Sand roasting machine | 【Continuous type】 Place heated sand and raw materials in a roasting machine and roast them. |
・Easy to get heat into the core, but difficult to control ・Easy to swell ・Sand may adhere to the product |
About our roasting machines
roasting methods so that we can select the best roasting method for each material. By using the roasting machine best suited to the characteristics of
the material and the flavor required, we are able to maximize quality and provide high-quality raw materials that meet the needs of our customers.
Below is an introduction to the roasting machines we own.
Fluidized type triple hot air roasting machine
- Barley
- Rice
- Malt
Three fluidized hot air roasting machines are used in succession to increase product temperature, expansion,
and roasting color.
We mainly produce roasted products for beverage
ingredients.
■Feature
① Short-time roasting at high temperature is possible
② High manufacturing throughput
③ Raw materials easily swell
Batch-type hot-air roasting machine
- Barley
- Pearl barley
- Corn
Raw materials are fed into a heated rotating drum, and
hot air is applied to roast the raw materials.
We mainly produce roasted barley and pearl barley for
beverage use.
■Feature
① High calorific value and short roasting time
② Capable of producing hard roasted products
Batch-type drum direct-fired roasting machine
- Green tea
- Foliar material
- Rice bran
The only heat source is a burner that strikes from below
the drum. The heated drum rotates to roast the material.
The machine roasts raw materials for beverages, food
products, and herbal medicines.
■Feature
① Low heat and non-stick
② Ideal for roasting leafy greens
Fluidized type triple sand roasting machine
- Barley
Heated sand is circulated in the roasting machine and the raw material is put into the machine.
The far-infrared effect of the heated sand roasts the raw material to its core.
Currently, only roasted barley for barley tea is produced.
■Feature
① Surface does not burn easily
② Enables fluffy roasting to the core
Batch-type semi-direct roasting machine
- Barley
- Pearl barley
- Soy bean
- Black soy bean
A hot burner heats the drum from below to roast the raw materials.
Hot air enters from the side, so dry hot air is circulated.
■Feature
① Surface does not burn easily
② Ideal for roasting beans
③ Capable of producing hard roasted products
Fluidized hot air roasting machine
- Barley
- Rice
- Cereals
For food compatibility, we use a stainless steel flow type hot air roasting machine.The machine has been
converted to a hot-air roasting machine specialized for
puffing processing, and puff products can be manufactured.
■Feature
① Short-time roasting at high temperature is possible
② Mainly for food raw materials
③ Puff products can be manufactured.
