Torreya is a unique mountain nut that is crispy, sweet, and nutritious. But the shell of the Chinese fir is thin and crispy, and the kernels are full. It is afraid of bumps and sudden heat, and the processing method directly affects the damage rate, appearance, taste, and storage time of the nuts. Let's use this article today to compare the traditional drum frying and microwave tunnel baking processes.
1、 Traditional drum frying machine for stir frying
Traditional drum frying relies on high-temperature flipping and material friction and impact to complete maturation, and is also the most common method for street side frying and small workshops.
Advantages
Continuously stir frying at high temperatures, the Maillard reaction is complete, and the smoky aroma is very rich, which is the familiar old-fashioned stir fry aroma to the public. The taste is thick and highly recognizable. The device has a low threshold and is suitable for small batches and spot trading.
shortcoming
The first issue is frequent damage and cracking, with a high rate of defects. The drum keeps rolling and colliding with each other, making the outer shell of the camphor tree extremely susceptible to pressure and squeezing. During large-scale frying, it is easy to experience shell cracking, peeling, cracking, and kernel exposure. There are many broken and cracked fruits, and the finished products are sold unevenly, resulting in significant loss during grading and screening.
The second is uneven heating, which belongs to external heat conduction heating. The shell temperature is extremely high, making it easy to fry black and burnt, but the inside of the nuts cannot be fully dried, and they are cooked outside and cooked inside, with varying degrees of dryness and wetness. Causing some of the goods to be bitter, some to be undercooked, and the taste to be unstable.
At the same time, prolonged high temperatures can accelerate the oxidation of oils and fats, making nuts prone to a rancid taste. They are also prone to moisture, insect infestation, and spoilage during later storage, resulting in a shorter shelf life.
2、 Microwave tunnel oven baking
Advantages
There is no mechanical impact during microwave baking, and the damage rate is extremely low.
The materials are conveyed flat and gently through the equipment, without high-intensity rolling friction, squeezing and collision. The outer shell of the camphor tree is intact without cracking, peeling or exposing the kernels. The finished particles are full and neat, and the whole batch is sold uniformly. The loss of defective products is greatly reduced.
At the same time, microwave is a penetrating integral heating method, which synchronously dehydrates and matures the shell and kernel, solving the problem of external coke and internal growth. The ripeness is uniform, the dryness and wetness are consistent, and the crispness of the nuts is uniform, without the occurrence of half cooked or half burnt.
Low temperature rapid maturation, preserving the sweet and original fragrance of the Chinese fir as much as possible, with minimal loss of nutrients. And synchronized sterilization and insect egg killing, clean and hygienic, slow oil oxidation, less prone to cracking, moisture regain, mold growth, and longer shelf life.
shortcoming
Under mild heating conditions, high-temperature stir frying has a weak sensation, while traditional fireworks have a lighter burnt aroma, highlighting the natural flavor of nuts. People who do not like light taste may feel that the aroma is not heavy enough. The equipment is more suitable for large-scale production and not suitable for extremely small batch processing.
