The Angel Juicer mashing housing is a strainer without holes which can be used to create nut butters etc. The twin gears grind every ingredient in three stages and all will come out the same opening at the end of the strainer. This peanut butter strainer is made of stainless steel (SUS304) and is suitable for the Angel Juicer AG-5500, AG-7500 and AG-8500. The housing is also available in higher quality stainless steel (SUS316) from which the parts of the Angel Juicer AG-8500 are made. The function and fit are identical, making both housings suitable for the three Angel models.
