To find the number of pita sandwiches made per day, we first note that there are 4 types of bread. The total number of sandwiches produced each day is 364.
We divide the total number of sandwiches by the number of types of bread:
\[ \text{Number of sandwiches per type of bread} = \frac{364}{4} = 91 \]
Thus, the number of pita sandwiches made per day is:
\[ \boxed{91} \]
